In fact, you have come to the right place in your quest to learn about the instruments of the Orchestra, and I assure you it will be worth your while.

By the end, you will have a deeper understanding of how these instruments are organized into families and how they collaborate harmoniously within the orchestra.

So, without any further delay, let us delve into the exciting world of orchestral instruments and uncover its wonders!

What Are the Instruments of The Orchestra?

The instruments of the orchestra are the musical tools used by musicians to perform in an orchestra.

The orchestra is a rich tapestry of sounds, with each instrument contributing its own unique voice. Together, they create beautiful and awe-inspiring music that has captivated audiences for centuries.

These instruments have different sounds and ways of producing sound, but when they come together, they create amazing and historically informed performances.

The instruments of the orchestra are grouped into families based on how they produce sound and their unique characteristics. There are five main groups: strings, woodwinds, brass, percussion, and keyboards.

In an orchestra, instruments from the same family are often grouped together and sit in the same section.

For example, all the string instruments like the violin, viola, cello, and double bass sit together, while the woodwind instruments like the flute, clarinet, and oboe have their own section.

Likewise, the brass instruments such as the trumpet, trombone, and French horn also sit together.

Also, the percussion instruments, like drums and cymbals, are usually grouped in the percussion section.

Finally, the keyboards, such as the piano and organ, have their designated place in the orchestra.

Besides these commonly found instruments, there are other instruments that are occasionally used in the orchestra.

These include the saxophone group and instruments from earlier periods like the harpsichord, oboe d’amore, recorder, and basset horn.

There are also specialized brass instruments like the Wagner tuba, cornet, and euphonium.

The percussion section offers a wide variety of instruments such as sleigh bells, gongs, woodblocks, marimbas, claves, maracas, bongo drums, and cowbells.

Additionally, electronic instruments like the electric organ, electric guitar, and synthesizer can also be incorporated into orchestral performances.

String Instruments in The Orchestra

String instruments are a category of musical instruments that produce sound through the vibrations of stretched strings.

These instruments typically have strings that are placed over a resonating body or a hollow chamber, which amplifies the vibrations and generates sound.

The strings can be made of materials like gut, nylon, steel, or metal.

String instruments play a fundamental and essential role in the orchestra.

They work together to create the melodic and harmonic foundation of the orchestra’s music, offering a wide range of sounds, from gentle and tender melodies to lively and virtuosic passages.

The strings often take on prominent roles, carrying the main themes and adding depth and richness to the overall sound.

In addition to their individual contributions, the string instruments frequently play in unison or harmonize with one another, resulting in a lush and blended sound.

The interaction between the strings and other sections of the orchestra, such as the woodwinds, brass, and percussion, adds depth and complexity to the music.

The string family encompasses a diverse range of instruments, each with its own distinct characteristics and playing techniques.

They are further classified as bowed strings and unbowed string instruments.

Bowed Strings

The bowed string instruments, including the violin, viola, cello, and double bass, create sound by drawing a bow across the strings.

Musicians can also pluck, strike, or strum the strings to produce music.

Each instrument has a unique sound that is influenced by factors such as its shape, the type of wood used, the thickness of its top and back, and the varnish applied to its surface.

Craftsmen create these instruments by gluing pieces of wood together, forming a hollow sound box.

All the instruments in this family feature four strings, which can be made of materials like gut, synthetics, or steel.

The strings are attached to pegs at one end of the instrument and stretched tightly across a bridge.

They are then connected to a tailpiece at the other end. Musicians use the pegs to tune the instrument and adjust the string length, resulting in the desired sound.

The strings are tuned at specific intervals relative to each other.

When a musician presses a finger on the strings along the instrument’s neck, they change the length of the vibrating part of the string, producing different notes.

The shorter the vibrating section, the higher the pitch. This technique allows musicians to create melodies and play different musical tones.

Let’s take a closer look at the string family and the instruments that belong to it.


The violin, a small and agile instrument, produces beautiful and expressive sounds.

It holds the distinction of being the highest-pitched instrument in the string family and is played using a bow.

A violin typically possesses four strings, although some may have more, and these strings are usually tuned in perfect fifths, giving rise to notes like G3, D4, A4, and E5.

The primary method of playing the violin involves drawing the bow across the strings, producing a melodic sound.

However, the strings can also be plucked with the fingers (pizzicato) or even struck with the wooden side of the bow (col legno) in special circumstances.

Violins hold a significant role in orchestras, particularly in Western classical music.

They find common use in ensembles ranging from small chamber groups to large orchestras.

Furthermore, violins exhibit versatility as instruments that can be found in various musical genres and often assume solo roles.

Within an orchestra, violins are organized into two sections: Firsts and Seconds.

All first violinists play the same part, as do all second violinists, unless specified otherwise in the sheet music.

The leader of the First Violins also assumes the role of orchestra leader.

The number of violinists may vary, but typically there are sixteen Firsts and fourteen Seconds, with two violinists sharing a desk.

The violin possesses remarkable qualities that contribute richness and depth to the orchestra’s music.

Its versatility and expressive capabilities make it a treasured instrument in the realm of music.


The viola is another string instrument found in the orchestra’s string section. It closely resembles the violin but is slightly larger in size.

Similar to other bowed instruments, the viola is played with a bow or can be plucked using different bowing techniques.

The sound produced by the viola is lower, deeper, and richer compared to the violin.

Unlike the violin, the viola has a different string arrangement. Its strings are tuned to C-G-D-A, starting from the highest string to the lowest.

This tuning is exactly one octave higher than the cello’s strings. While the viola shares the same three lower strings as the violin, its fourth string is tuned a fifth lower than the violin’s lowest string.

The viola has a warmer tone quality than the violin and often plays harmonies to support the violin’s melody.

It serves as the alto voice of the string family, adding a warm and mellow quality to the orchestra’s overall sound.

In a typical symphony orchestra, there are usually twelve violas seated two to a desk when performing large orchestral works.


The cello, also known as the violoncello, rests on the ground when played.

Unlike the violin and viola, which are held on the shoulder, cellists play the cello in an upright position.

Cellists sit on a chair with the cello positioned between their legs and draw the bow across the strings to produce sound. They can also pluck the strings with their fingers.

The cello is equipped with an end pin that rests on the floor, providing support for the instrument’s weight.

Like other instruments in the violin family, the cello has four strings tuned in fifths to C2-G2-D3-A3, one octave lower than the viola.

Its lower strings create a deep, rich, and dark sound that closely resembles the human voice.

When cellists combine a broad vibrato with the cello’s deep tenor voice, they create a haunting and unique sound.

The cello also has a special ability to evoke a melancholic atmosphere. It does this more effectively than any other instrument.

Its wide range and powerful sound allow it to transition seamlessly from playing bass lines to soaring melodies that rise above the rest of the orchestra.

Besides, one remarkable quality of the cello is its clarity of attack, which enables it to produce precise musical shapes and drive rhythmic patterns.

This characteristic makes the cello an essential component of the orchestra’s “engine room,” providing a strong foundation and propelling the music forward.

Typically, a symphony orchestra includes between eight and twelve cellos, contributing to the ensemble’s rich and harmonious sound.

Double Bass

The double bass, also known as the bass, is the largest and deepest bowed string instrument.

It generates the lowest-pitched sound among the string instruments in the symphony orchestra, excluding unique additions such as the octobass.

It actively participates as a standard member of the orchestra’s string section, alongside the violins, viola, and cello.

Additionally, it frequently finds its place in concert bands and contributes to various musical compositions, including concertos, solos, and chamber music within the Western classical tradition.

Bassists typically play the double bass in an upright position, using either a bow or their fingers. Similar to the cello, they have the flexibility to stand or sit on a high stool.

The double bass structurally resembles the cello, sporting four strings with the possibility of having five at times.

In contrast to other string instruments, the double bass follows a tuning pattern in fourths rather than fifths.

Its strings are usually tuned to E1, A1, D2, and G2, resulting in a sound that resonates an octave lower than the written music.

Typically, a symphony orchestra includes between five and ten double basses, contributing a deep and resonant tone to the ensemble’s rich and harmonious sound.

The instrument’s resounding and robust sound serves as a steadfast foundation within the orchestra.

While the double bass occasionally takes center stage with solos or prominent parts, its primary purpose is to support the harmonies.

Additionally, the double bass establishes rhythmic foundations and enhances the overall orchestral sound in the background.

Endnote About Bowed String Instruments

The sound produced by bowed strings is often warm, expressive, and capable of evoking a range of emotions.

The violin produces the highest-pitched sound, while the viola has a slightly deeper tone.

The cello possesses a rich and resonant sound, and the double bass produces the lowest notes, providing a solid foundation for the orchestra.

Throughout their history, orchestras have usually had more bowed string instruments than wind or percussion instruments.

This is because the sound produced by bowed strings is softer, and it would be overshadowed by the louder sounds of the other instruments.

String players dedicate years to honing their craft in order to achieve mastery and master the technique and skill required to play these instruments, which is highly demanding.

Unbowed Strings

Unbowed string instruments belong to a category of musical instruments that produce sound without using a bow.

They offer alternative methods of creating music without the use of a bow.

Instead of relying on a bow to create sound, these instruments are played by plucking, striking, or strumming the strings.

One of the most widely recognized unbowed string instruments is the harp.

The harp has multiple strings that musicians pluck with their fingers, resulting in beautiful and melodic tones.

Another important unbowed string instrument is the piano. It contains strings that are struck by hammers when the keys are pressed.

Both the harp and the piano contribute to the rich tapestry of sounds in an orchestra.

Their unique characteristics and expressive capabilities make them integral parts of musical compositions, adding depth and emotion to performances.

The Harp

The harp is one of the most commonly used unbowed string instruments in the string family.

It features a triangular shape and is primarily made of wood. The strings of the harp can be made of materials like gut, wire, nylon, or metal.

Each string is attached to the crossbar or neck of the harp, where it has a tuning peg to adjust its pitch.

The string then extends down to the resonating body’s sounding board, where it is secured with a knot.

In modern harps, an eyelet is used to protect the string’s hole and prevent damage to the wood.

The pitch of each string is determined by factors such as the distance between the tuning peg and the soundboard, as well as the tension and weight of the string.

When playing the harp, musicians pluck the strings with their fingers.

The act of plucking a taut string causes the hollow body of the harp to resonate, creating a sound that projects outward.

The harp is known for its enchanting and ethereal sound. Its strings produce soothing melodies that can evoke a sense of tranquility and beauty.

While the harp is commonly associated with orchestral and classical music, it is also used in various other genres, including folk, Celtic, and contemporary music.

The Piano

This is another significant unbowed string instrument in the orchestra.

Although it belongs to the string family, the piano is typically classified as a percussion instrument in the orchestra.

The piano features strings that are struck by hammers when the keys are pressed.

It has a wide range of notes and is capable of producing both soft and powerful sounds.

The piano is a versatile instrument that plays a central role in many other styles of music, from classical to jazz and pop.

Woodwind Instruments of The Orchestra

Woodwind instruments use air blown through a tube with a mouthpiece or reed to produce sound.

These instruments have a tube-like shape with an open end and a mouthpiece at the other end.

Metal caps called keys cover rows of holes on the instrument. When players press different keys, the instrument produces various musical notes.

The sound changes depending on where the air exits the instrument, either through one of the key holes or at the far end.

People call them woodwinds because they are traditionally made from wood, although modern instruments can be made of metal, plastic, or other materials.

Woodwind instruments are capable of playing melodies and creating a wide range of tones and colors.

Some common woodwind instruments are the flute, clarinet, oboe, bassoon, English horn, and piccolo.

We also have the bass clarinet and contrabassoon as members of the woodwind instruments in the orchestra. Each instrument has its own unique sound and playing technique.

The woodwind family creates sound using three different methods.

First, by blowing air across the edge of or into the mouthpiece, as players do with the flute or piccolo.

Second, by blowing air between a single reed and a fixed surface, like in the case of the clarinet and bass clarinet.

And third, by blowing air between two reeds, which is how the oboe, English horn, bassoon, and contrabassoon produce sound.

Apart from the flute and piccolo, the other woodwind instruments belong to the category of reed instruments.

These can be further divided into single reeds and double reeds, which share the common characteristic of producing sound through the vibration of reeds.


The flute belongs to the woodwind family of musical instruments. It is known for being the highest-pitched instrument in the woodwind section and is one of the most well-known members of this group.

Similar to other woodwind instruments, the flute is classified as an aerophone, as it produces sound through the vibration of air.

However, unlike instruments with reeds, the flute produces sound when the player blows air across an opening.

In the Hornbostel-Sachs classification system, flutes are categorized as edge-blown aerophones. While old flutes were made of wood, most modern flutes are made of metal.

The flute is primarily a melodic instrument within the woodwind family. It has a soft and airy sound that is created by blowing air across its mouthpiece.

When air is directed across a hole in the instrument, it causes the air at the hole to vibrate. This vibration is created by the airflow, creating a Bernoulli or siphon effect.

The vibration excites the air inside the resonant cavity of the flute, which is usually cylindrical in shape.

The flutist can change the pitch of the sound by opening and closing holes in the flute’s body, thereby altering the effective length of the resonator and its corresponding resonant frequency.

Additionally, by varying the air pressure, a flutist can produce harmonic frequencies without adjusting the holes.

There are several types of flutes commonly used in orchestras, including the C flute, piccolo, alto flute (in G), and sometimes the bass flute.

In addition to its ability to showcase virtuosity, the flute is capable of creating beautiful sustained melodies.

It has a bright tone and blends well with other instruments. The flute often provides background color to the main musical activity happening elsewhere in the orchestra.


The piccolo, a smaller version of the flute, belongs to the woodwind family.

It is commonly made of metal or wood and is sometimes called a “baby flute” due to its shorter length.

The modern piccolo functions similarly to the regular transverse flute and has similar fingerings. However, the piccolo produces a sound that is one octave higher.

The piccolo serves as a specialty instrument, specifically employed when music requires high pitches.

When flute players need to play exceptionally high notes, they often switch to the piccolo.

It frequently doubles the violins or flutes in orchestras, contributing a sparkling and brilliant quality to the overall sound.

The piccolo is a standard instrument found in orchestras, marching bands, and wind ensembles.


The oboe is another instrument in the woodwind family that is distinguished by its double reed.

It is typically made of wood, although synthetic materials like plastic, resin, or hybrid composites can also be used.

To play the oboe, musicians blow air into the double reed, applying enough pressure to make it vibrate within the instrument’s air column. This creates a distinct and often described “bright” tone.

Oboes have been an integral part of orchestras for approximately 400 years and hold a prominent position in the woodwind section.

They have a slightly lower pitch than the flute, occupying the alto register.

Today, the oboe is widely used in symphony orchestras, concert bands, and chamber ensembles, both as a solo instrument and as part of the ensemble.

Typically, a symphony orchestra includes between one and three oboes.

They contribute their unique sound to create rich, beautiful melodies and harmonies for the ensemble.

English Horn

The English horn, known as the cor anglais in French, is a double-reed woodwind instrument that belongs to the oboe family.

It is approximately one and a half times longer than an oboe, giving it the role of an alto oboe in the key of F.

The instrument is often called the cor anglais in French, for reasons that are somewhat unclear.

One notable feature of the English horn is its distinct pear-shaped bell. The pear-shaped bell, known as the Liebesfuß, gives the English horn a more covered timbre compared to the oboe.

This double-reed woodwind instrument possesses a tonal quality closer to that of the oboe d’amore.

While the oboe is recognized as the soprano instrument of the oboe family, the English horn is generally considered its alto counterpart.

In a symphony orchestra, it is customary to have one English horn.

It plays a soothing melodic role and adds a softening effect to the overall texture of the wind section.


The clarinet, belonging to the woodwind family, is another wooden instrument in the orchestra. It takes on an almost cylindrical shape with a wide opening at one end.

When someone blows air between the mouthpiece and a single reed, the clarinet produces a smooth sound. As the air passes through, the reed vibrates and creates the sound we hear.

Forming a family of instruments, clarinets come in different sizes and pitches. In fact, they hold the title of being the largest among the woodwind instruments, ranging from the BB♭ contrabass clarinet to the E♭ soprano clarinet.

With a range spanning almost four octaves, the clarinet proves to be a highly versatile instrument. The tone quality can vary greatly, influenced by factors such as the musician, the instrument itself, the mouthpiece, and the reed used.

Today, orchestras commonly feature the clarinet. Typically, a symphony orchestra includes one to three clarinets as part of its ensemble.

What’s interesting is that clarinets have the ability to produce both loud and soft sounds, surprising many with their dynamic range.

Bass Clarinet

The bass clarinet belongs to the clarinet family and is a single-reed musical instrument.

Most modern bass clarinets have a straight body, a small silver-colored metal bell that curves upward, and a curved metal neck where the mouthpiece is attached.

In the past, they had different shapes, with some even having a double body resembling bassoons.

The bass clarinet is quite heavy and can be supported either by a neck strap or an adjustable peg attached to its body.

Just like other clarinets in the family, the majority of modern bass clarinets use the Boehm system of keys and fingering.

Similar to the more common soprano B♭ clarinet, the bass clarinet is typically pitched in B♭.

This means that it is a transposing instrument, where a written C sounds like a B♭ when played. However, it produces notes one octave lower than the soprano B♭ clarinet.

Although bass clarinets in other keys, such as C and A, exist, they are very rare compared to the more common A clarinet in classical music.

Nevertheless, the bass clarinet shares the warm and rich sound quality of the higher-pitched clarinets, creating a comforting and satisfying tone.

Bass clarinets are regularly featured in orchestras, and it is customary to have at least one bass clarinet in a symphony orchestra.


The bassoon is a woodwind instrument in the woodwind family that plays in the tenor and bass ranges.

It is renowned for its distinctive tone color, wide range, versatility, and virtuosity.

The bassoon consists of six pieces and is typically made of wood. Among the woodwind instruments, the bassoon holds the position of the lowest-sounding member and exhibits remarkable versatility.

It starts its range at B♭1, which is the first note below the bass staff. This range extends over three octaves, reaching approximately the G above the treble staff (G5).

However, most music composed for the bassoon rarely calls for notes above C5 or D5.

The bassoon produces a rich, slightly buzzing quality in the lower ranges and a sweet, nasal sound in the higher ranges.

It is a non-transposing instrument, and composers usually write its music in the bass and tenor clefs, occasionally using the alto or treble clef.

Two primary forms of the modern bassoon exist: the Buffet (or French) system and the Heckel (or German) system.

The bassoon is commonly played while seated, using a seat strap, although it can also be performed while standing if the player has a harness to support the instrument.

To produce sound, the player positions both lips over the reed and blows air with direct pressure, causing the reed to vibrate.

The fingering system of the bassoon can be quite complex when compared to that of other instruments.

The bassoon, in its modern form, emerged in the 19th century and continues to play a prominent role in orchestras.

It is common for a modern symphony orchestra to have between two and three bassoon players.

As solo instruments, bassoons can be highly expressive, and their warm vibrato allows them to sound remarkably human, resembling a resonant baritone singer.


The contrabassoon, also known as the double bassoon, is a large and low woodwind instrument.

It is much longer than the regular bassoon and curves around itself twice.

Due to its weight and shape, it is supported by an end pin and sometimes a strap around the player’s neck for additional support.

The contrabassoon produces a very deep sound, playing an octave lower than the bassoon.

It shares the sub-bass register with instruments like the tuba, double bass, or contrabass clarinet.

The technique of playing the contrabassoon is similar to that of its smaller cousin, but with some notable differences.

For example, the reed used for the contrabassoon is considerably larger than the one used for the bassoon.

The contrabassoon has a wide range, starting at B♭0 and sometimes even at A0 on certain instruments.

It extends over three octaves, reaching up to D4. However, the highest notes are rarely utilized in compositions.

While the contrabassoon has a similar tone to the bassoon, it has a distinct sound throughout its entire range.

In its lowest register, it has a booming quality similar to organ pedals, allowing it to produce powerful contrabass tones, aided by the flared bell that the bassoon lacks.

In a symphony orchestra, it is customary to have one contrabassoon. It is considered a supplementary instrument rather than a core part of the orchestra and is most commonly found in larger symphonic works.

Brass Instruments of the Orchestra

Instruments of the Orchestra - French Horn

Brass instruments are a group of musical instruments commonly found in orchestras.

They are like long pipes made of brass or other metals that widen into a bell shape at the end.

These instruments have been shaped and twisted to make them easier to hold and play.

When playing brass instruments, the musician buzzes their lips into a cup-shaped mouthpiece, creating a unique and distinct sound.

Most brass instruments have valves attached to their pipes. By pressing the valves, different parts of the pipe open and close, changing the length and producing lower or higher sounds.

The musician can also adjust their lip position and tension to select different pitches.

In addition, we can insert mutes into the bell of a brass instrument to change the sound’s timbre.

The brass section of an orchestra usually includes instruments such as the trumpet, trombone, French horn, and tuba.

Brass instruments in the orchestra have various roles. They provide harmonic support, play melodies, and add power and brilliance to the overall sound.

They are essential for creating a dynamic and vibrant orchestral texture.

French Horns

The French horn, also known as the horn in professional music circles, is a brass instrument commonly found in orchestras.

It has a unique shape, with tubing wrapped into a coil and a flared bell.

French horns have a tightly coiled pipe that is remarkably long, measuring about 18 feet.

This makes it one of the longest brass instruments in terms of pipe length!

The most commonly used horn in professional orchestras and bands is the double horn in F/B♭, which is technically a type of German horn.

However, the descant and triple horn have been gaining popularity.

When playing the Horn, the bell points away from the audience, setting it apart from other brass instruments.

The player produces different notes by pressing valves with the left hand and manipulating the right hand inside the bell.

The French horn has an impressive range, spanning from deep bass notes to high melodies. Many consider it to be the most beautiful-sounding instrument in the orchestra.

The mellow sound of the horn has the power to transform a simple tune into something that soothes and uplifts the spirit.

French horns can also produce a tremendous volume, breaking through any orchestral texture when the whole section plays loudly.

Composers commonly feature the horn in orchestras and concert bands to utilize its unique tone and create specific musical effects.

The horn is often used in music to provide harmonic filling, occupying a place between the bass line and the melody.

A classical orchestra typically includes a minimum of two French horn players. The first horn player performs the higher parts, while the second horn player takes on the lower parts.

A typical symphony orchestra includes six to eight horns as part of its ensemble, contributing to the rich and dynamic sound of the orchestra.


Instruments of the Orchestra - Trumpet
Venezualan trumpet player Pacho Flores

The trumpet is a popular brass instrument that is commonly used in classical music and various other genres.

It has a long history, dating back to around 1500 BCE, although it was initially used for signaling and religious purposes due to its bright and clear sound.

It wasn’t until the late 14th or early 15th century that it started being used as a musical instrument.

The trumpet family includes various types of trumpets, ranging from the piccolo trumpet with its high register to the bass trumpet, which is pitched one octave below the standard B♭ or C trumpet.

To play the trumpet, the musician blows air through slightly separated lips, creating a buzzing sound that sets off vibrations in the air column inside the instrument.

The air travels through about six and a half feet of tubing that is bent into an oblong shape.

Modern trumpets have three valves that can be pressed to change the pitch, a feature that was added in the early 19th century.

Most trumpets have piston valves, although some have rotary valves, which are more commonly used in orchestral settings, particularly in German and German-style orchestras.

The trumpet is widely recognized as one of the most well-known brass instruments.

It is also one of the loudest instruments in an orchestra, capable of being louder than an entire section of string instruments.

However, in the hands of a skilled orchestral player, the trumpet can display a great deal of flexibility and versatility.

Trumpets are renowned for their fanfare-like sound and are often used to lead and play melodic parts in music.

A typical symphony orchestra usually includes three to five trumpets as part of its ensemble.


The trombone is a musical instrument from the brass family. It consists of a mostly cylindrical brass tube with two bends shaped like the letter “U” and a flared bell at the end.

The tubing is actually a combination of different tapers that affect the instrument’s intonation.

Like other brass instruments, the trombone produces sound when a player blows air through pursed lips, creating vibrations that generate a standing wave inside the instrument.

What sets the trombone apart is its slide, which allows the player to adjust the tubing length and alter the pitch.

Lengthening the tubing lowers the pitch, and there is a short tuning slide for intonation adjustments.

Unlike brass instruments that utilize valves, trombones use a slide mechanism to change the pitch. Players move the slide in and out to produce different notes.

Trombones come in different sizes, including alto, tenor, and bass. The most common types are the tenor trombone and the bass trombone.

The tenor trombone is the standard instrument found in most brass sections. It plays at concert pitch in bass clef and is not a transposing instrument.

The tenor trombone is pitched in B♭, one octave lower than the B♭ trumpet and one octave higher than the B♭ bass tuba.

Trombones have a powerful sound when played loudly but can also produce a mellow tone when played softly.

One distinctive feature of the trombone is its ability to slide between notes, creating a glissando effect.

A typical symphony orchestra typically includes three to five trombones in its ensemble.

Bass Trombone

The bass trombone, similar in length to the tenor trombone but with a longer slide, features double tubing, a wider bore, and a larger bell.

It is specifically designed to play the bass lines in the brass section, providing a rich foundation for the ensemble’s sound.

In addition, the bass trombone may have one or two valves that allow the player to lower the instrument’s key, expanding its range and versatility.

These valves provide extra notes and enable smooth transitions between different pitches.

What sets the bass trombone apart is its ability to produce a velvety smooth sound in the higher register while still maintaining a strong and robust lower range.

This versatility allows the bass trombone to adapt to various musical styles, including swinging jazz and classical symphonies.

A symphony orchestra typically includes at least one bass trombone, ensuring the powerful and resonant bass lines are effectively conveyed.

The bass trombone adds depth and richness to the overall orchestral sound, creating a harmonious balance among the different sections.


Instruments of the Orchestra - Tuba

The tuba is the lowest-pitched instrument in the brass family. It first appeared in the mid-19th century, making it one of the newer instruments in the orchestra and concert band.

All tubas are conical in shape, meaning the diameter of the tubing increases from the mouthpiece to the bell.

This conical bore gives the tuba its unique sound, emphasizing even-order harmonics.

There are different types of tubas, including the high B♭ tenor tuba, the BB♭ bass tuba, and the BB♭ contrabass tuba.

Each type varies in size but follows a similar construction.

The sound of the tuba is produced by buzzing the lips into the mouthpiece, just like with other brass instruments.

The vibrations created travel through the long tubing, which can be approximately 18 feet in length.

The length of the tubing determines the pitch of the notes played.

To achieve a wider range of notes, tubas are equipped with valves. A concert tuba typically has four or five valves.

These valves introduce additional tubing lengths, allowing the player to play a full chromatic scale.

In an orchestra, there is usually a single tuba, although there may be instances where an additional tuba is needed.

The tuba serves as the bass of the brass section and adds depth and power to the overall sound of the orchestra.

It also reinforces the bass voices of the strings and woodwinds.

Composers often rely on the tuba to provide a symphonic sound with its power and depth.

Its warm and rich tone adds a unique quality to the music. The tuba’s role within the orchestra is vast and varied, making it an integral part of the ensemble.

Percussion Instruments of The Orchestra

Percussion instruments are a group of musical instruments that make sound when they are struck, shaken, or scraped.

They are important in various types of music, including orchestral and popular music.

Percussion instruments have a vital role in creating rhythm, texture, and accents in music.

They establish the beat and keep time, providing a foundation for other instruments to follow.

In addition to being used in traditional ensembles, percussion instruments are also common in contemporary music genres like rock, pop, jazz, and world music.

They bring energy, excitement, and unique sounds to compositions, making performances more captivating.

Percussion instruments come in various shapes, sizes, and materials, each producing its own unique sounds and effects.

There is a wide variety of instruments, which can be divided into two main groups: tuned percussion and untuned percussion.

Tuned percussion instruments are capable of playing specific notes, similar to woodwind, brass, and string instruments.

Additionally, there are certain keyboard instruments, like the piano, that belong to a distinct category within the percussion instrument family.

Untuned percussion instruments produce sounds without a definite pitch, such as when you strike two pieces of wood or metal together.

Percussion instruments are found in various cultures around the world, representing different musical styles.

Some common examples of percussion instruments include drums, cymbals, tambourines, maracas, xylophones, triangles, and gongs.

Besides, some keyboard instruments, such as the piano, belong to a distinctive category within the percussion instrument family.

Tuned Or Pitched Percussion Instruments

Pitched or tuned percussion instruments are a specific type of percussion instrument that can produce specific pitches or notes.

These instruments have fixed pitches and are played by striking specific keys, bars, or membranes that are tuned to specific frequencies.

Pitched percussion instruments are often used to play melodies, harmonies, and chords in musical compositions.

They add tonal color and musicality to the overall sound of an ensemble or performance.

Examples of pitched percussion instruments include the timpani, xylophone, triangle, marimba, vibraphone, and many others.


Timpani are large percussion instruments that produce deep, pitched sounds.

They are also known as kettledrums or “timps” and are tuned to specific notes that correspond to the key of the music being played.

A set of timpani is called a “timpani,” while a single drum is called a “timpano.”

The basic timpano consists of a drum head stretched across a bowl made of copper, fiberglass, or aluminum.

Most timpani have pedals that can change the pitch. The most common type used today are pedal timpani, which allow the tension of the drum head to be adjusted using a pedal mechanism.

The pedal is connected to the tension screws through a metal assembly called the spider.

Timpani sticks, also known as timpani mallets, are used to strike the drums. They are used in pairs and have a shaft and a head.

The shaft is typically made of hardwood or bamboo, while the head is made of felt wrapped around a wooden core.

To produce a note, the performer strikes the top of the drum with timpani mallets. The larger the drum, the lower the sound it produces.

A standard set of timpani, known as a console, consists of four drums with diameters of approximately 32 inches, 29 inches, 26 inches, and 23 inches.

The range of this set is roughly from the note D2 to the note A3.

A typical symphony orchestra usually includes two to four timpani in its ensemble.

Standard orchestras have included at least two timpani since around 1700, and it is common to have three or four timpani played by a single percussionist.

Timpani are highly versatile and can even play melodies.

They serve as the rhythmic foundation of the orchestra, and conductors often maintain constant eye contact with the timpanist.


The xylophone is a percussion instrument that features wooden bars arranged in two rows, resembling the black and white keys of a piano.

In modern xylophones, the bars are commonly made of materials such as rosewood, padauk, or synthetic materials, enabling them to produce a louder sound.

When we strike the bars with beaters, they produce chromatic notes, allowing us to play different pitches.

By using different types of mallets and striking the bars in different ways, we can change the pitch’s quality.

In orchestral xylophones, there are metal tubes fixed beneath the bars, serving as resonators.

These resonators contribute to the xylophone’s bright and bell-like sound.

Although the xylophone has been used in Europe since the sixteenth century, it was primarily used for special effects.

It was considered a novelty instrument until the middle of the nineteenth century, when improvements in tuning and tone made it a part of the percussion section in symphony orchestras.

Xylophones can vary in size, with some having a range of two and a half octaves, while concert xylophones typically have three and a half or four octaves, starting from middle C.

It’s important to note that the xylophone is a transposing instrument, meaning its written parts are one octave below the sounding notes.


Chimes are musical instruments that belong to the percussion family. They consist of a set of metal tubes that are suspended and arranged in rows.

Each tube produces a different pitch, creating a melodic and bell-like sound.

The arrangement of chimes is similar to the layout of a keyboard, with two rows resembling the black keys on a piano placed higher at the back.

This design allows the player to easily reach and play each note.

To play the chimes, a mallet made of rawhide or hard plastic is used to strike the top edge of the tube. The choice of mallet affects the tone produced.

A softer mallet produces lower tones and reduces the prominence of higher partials, resulting in a darker sound.

On the other hand, striking the chimes with a harder mallet brings out the higher overtones, creating a brighter and more distinct sound.

What makes chimes unique is how our ears perceive their sound. The pitch we hear is actually one octave below the fundamental pitch produced by the chime.

When reading musical notation, the written pitches represent the strike note, not the actual sound we perceive.

Additionally, the overtones produced by chimes differ from the usual linear set of harmonics found in most instruments.

This combination of factors contributes to the distinct timbre and character of chimes.

Even in the presence of a full orchestra, concert band, or percussion ensemble, chimes can be easily distinguished due to their unique timbre.

Their melodic and bell-like tones stand out, adding a beautiful and enchanting quality to the music.


The marimba is a percussion instrument that consists of wooden bars or slabs that are struck by mallets.

Each bar has a resonator pipe beneath it, which amplifies specific harmonics of its sound.

The resonators of a marimba should be tuned to match the frequency of the bars.

Many marimbas have tunable resonators, which ensure a high-quality sound regardless of the climate conditions in different locations.

Compared to the xylophone, the marimba has a warmer, deeper, and more resonant timbre. It also has a lower range.

The bars of a marimba are typically arranged chromatically, similar to the keys of a piano. The marimba falls under the category of idiophones.

Marimba bars are made from materials like kelon, padauk, or Honduran rosewood in professional instruments.

Rosewood is preferred for its range and ability to produce warm sounds.

To play the marimba, the wooden bars are struck with mallets that have a wrapped head. Soft rubber or yarn-wrapped mallets are commonly used to produce the desired sound.

The range of a marimba can vary widely, from 3 octaves to 5 or more.

The marimba instrument sounds as written and has become the standard keyboard concert instrument in the percussion family.


The Vibraphone is a percussion instrument with tuned metal bars that was invented in the 1920s. It is commonly used in orchestras.

The vibraphone looks similar to other percussion instruments like the xylophone and marimba. It has a keyboard-like layout with two rows of aluminum bars instead of keys.

Each metal bar on the vibraphone has a hanging metal tube beneath it, which acts as a resonator.

These tubes strengthen the vibrations of the bars. Each resonator tube has a paddle-shaped fan attached to it.

An electric motor makes the fans rotate, causing the tops of the tubes to open and close. This creates a vibrato effect, where the pitch of the sounds produces waves.

The vibraphone also has a pedal-operated damping mechanism that can silence a note or chord when a new one is played.

The use of pedals and damping is unique to the vibraphone, as is the motor that provides the vibrato effect.

To play the vibraphone, musicians use a mallet that usually has a rubber ball core wrapped in yarn or cord.

The mallet is attached to a narrow dowel, commonly made of rattan or birch and sometimes fiberglass or nylon.

They strike the metal bars with the mallet to produce sound.

The vibraphone typically has a range of three octaves, starting from F3 below middle C to F6 above middle C.

However, the exact range can vary depending on the instrument’s make and model.

When played, the vibraphone produces sounds as written in the sheet music.

It has a sweet tone and can be used to play broken chords resembling those of a harp, as well as other special effects.


The glockenspiel is a percussion instrument that has a set of metal bars arranged like a keyboard. The bars, usually made of steel or aluminum, are struck with mallets to make a sound.

The bars of the glockenspiel follow a chromatic scale, similar to piano keys. Each bar has its own pitch, and when you hit it, it creates a clear and bright sound.

The glockenspiel is commonly played in marching bands as well as in orchestras and various musical ensembles.

To hold the bars in place, the glockenspiel is usually attached to a frame or stand. In orchestras, the bars are mounted horizontally.

The size of the glockenspiel can vary, from just a few octaves to a smaller range.

The instrument generally plays in the higher register, covering about 2 to 3 octaves, though professional models may have a wider range.

When playing the glockenspiel, musicians use hard, unwrapped mallets made of metal or a strong type of plastic or synthetic material.

Metal mallets, usually made of brass or aluminum, create a bright sound, while rubber mallets can be used for a warmer tone.

Typically, non-metal mallets or a type of polymer such as Lexan or acrylic are used for general playing.

Glockenspiels are often used to play melodies, harmonies, and accompaniments in musical compositions.

By using a technique called the Stevens grip, it’s even possible to play chords with four mallets.

The glockenspiel is sometimes considered a transposing instrument, meaning it sounds two octaves higher than written music.

This difference in pitch can be indicated with a special clef.

With its distinct and vibrant sound, the glockenspiel adds a sparkling and percussive quality to the overall music.

Its high-pitched, clear tone is frequently heard in orchestras.

Untuned Or Unpitched Percussion Instruments

These percussion instruments do not produce specific pitches but instead contribute rhythmic patterns and add texture to the music.

Additionally, these instruments are utilized to provide accents, create intriguing sound effects, and enhance the overall rhythm and energy of the music.

Some examples of these percussion instruments include the bass drum, snare drum, tambourine, cymbals, shaker, triangle, wood block, claves, cowbell, gong, and castanets.

However, there are numerous other untuned or unpitched percussion instruments available.

It is worth noting that we won’t delve into those instruments in detail here, as they are less commonly used in orchestral compositions.

Bass Drum

The bass drum is a percussion instrument known for its large size and deep sound. It is the biggest member of the drum family.

When played, it produces a low note with either a definite or indefinite pitch.

In symphony orchestras, it is commonly referred to as the concert bass drum.

The bass drum has a cylindrical shape, with its diameter much larger than its depth. It features a striking surface on both ends of the cylinder.

Bass drums come in various sizes, ranging from 18 to 40 inches in diameter.

Concert bass drums, specifically used in symphony orchestras, have a diameter of 36 to 40 inches and are not tuned to a specific pitch.

They are usually mounted on folding stands or suspended stands. Achieving the desired sound requires careful muffling of the drum.

When playing the bass drum, musicians typically use a pair of large sticks with felt heads called mallets.

These mallets come in different shapes, including a general ball shape, a pair of rolling mallets, and an oval-shaped beater for a more fundamental sound.

The concert bass drum is the deepest drum in the percussion family.

Players need to explore the drum’s sweet spot, which is usually found by playing slightly off-center.

Considerations such as tuning, size, and the type of drumhead used also affect the sound.

In an orchestra, the bass drum serves multiple purposes. It creates impact during powerful moments and can imitate the distant rumble of something ominous.

Its deep and resonant sound adds depth and intensity to orchestral compositions.

Snare Drum

A snare drum is a percussion instrument with a cylindrical drum shell and tight drumheads on the top and bottom.

The drumheads are usually made of Mylar plastic in modern drums, but in the past, they were made from calf or goat skin.

The snare drum gets its name from the material stretched across the bottom drumhead, which creates a buzzing sound.

These materials, called snares, can be steel wires, cables, or other synthetic materials. The most common types are coils and cables.

The bottom drumhead, where the snares are stretched, is called the snare head.

Snare drums can have shells made of various materials, including metal or wood.

Metal shells are often made of steel, aluminum, or copper, and they produce a bright, sharp tone with a fast attack and long sustain.

Wood shells, made of woods like maple, birch, or mahogany, have a warm, dark tone with a round attack and maximum resonance.

Traditionally, metal shell snares are used in wind ensembles, while wood shell snares are used in symphony orchestras.

Snare drums come in different sizes, ranging from twelve to eighteen inches in diameter and three to twenty inches in depth.

The top drumhead, called the batter head, is struck to produce sound, causing the snares to vibrate against the snare head and create a rattling sound.

The snare drum is played with two sticks, typically made of wood.

It can also be played with sticks covered in felt or wire brushes that are rhythmically slid across the drumhead.

The snare drum is a central instrument in the percussion section and is used in both concert bands and orchestras.

In orchestral settings, snare drums are placed on concert stands, which can be adjusted for players who stand while playing.


Gongs, also known as Tam-tams, belong to the percussion family. They are large circular instruments made of metal alloy that are played by striking them with a soft mallet.

The sizes of gongs vary, ranging from approximately 20 to 60 inches or 50 to 150 cm in diameter.

Typically, gongs are made of a unique metal called bronze, which is a combination of tin and copper. However, other metals, like brass, can also be used.

Gongs are part of the percussion family, which includes instruments that are played by striking, shaking, or scraping.

Similar to cymbals, gongs are metal plates that have been shaped and hammered to a specific thickness so that they can make a resonant sound when struck.

When you hit a gong, it produces two different kinds of sounds. Flat-surfaced gongs vibrate in many different ways, creating a crashing sound without a specific musical pitch.

These gongs are sometimes called tam-tams, which helps to distinguish them from other gongs that produce specific musical notes.

The sound of a gong or tam-tam can change depending on how hard and quickly you hit it.

Gongs come in various shapes and sizes, ranging from small ones to very large ones that are bigger than a person.

When used in an orchestra, gongs create untuned sounds that can be either loud crashes or deep rumbles.

They are often used to add a sense of fear and suspense to dramatic scenes in music, especially in melodramatic pieces.

Whenever gongs are played, they bring a feeling of excitement and intensity to the music.


Cymbals are round percussion instruments made of different metals, especially copper-based alloys. The most common metals used for making cymbals are bronze, brass, and nickel-silver.

Cymbals are used in pairs and typically have diameters ranging from 13 to 22 inches.

Most cymbals produce an indefinite pitch, although there are smaller disc-shaped cymbals based on ancient designs that produce a definite note, like crotales.

Cymbals are used by percussionists in both Western and non-Western music. They are featured in various ensembles, including orchestras, concert works, and different genres of music.

In the orchestra, the commonly used cymbals are known as clash cymbals.

Traditionally, orchestral clash cymbals are used in pairs, and they have a strap attached to the bell of each cymbal for holding them.

These pairs are referred to as concert cymbals, clash cymbals, crash cymbals, hand cymbals, piatti, or plates.

Concert cymbals come in different sizes, ranging from approximately 14 to 22 inches in diameter, and they have various styles and weights.

They are played in pairs by holding one cymbal in each hand and striking them together to produce sound. Usually, crash cymbals are silenced or muted by pressing them against the percussionist’s body.

Cymbals provide composers with a wide range of colors and effects to work with.

They also offer a wide range of tones and volumes, making them versatile and capable of producing diverse sounds in musical performances.

The size of a cymbal directly influences the pitch it produces. Larger and heavier cymbals produce deep and rich sounds, while smaller and thinner cymbals create bright and high-pitched tones.

Their distinct sound allows them to stand out even in the presence of a full orchestra and amidst dense orchestrations.

They enhance articulation and can be played at various dynamic levels, offering composers limitless possibilities for expression.


The triangle is a metallic percussion instrument created from a metal rod and played by striking it with a small metal rod.

It is crafted from various metals like aluminum, beryllium copper, brass, bronze, iron, and steel. The metal is shaped into a triangular form with one open end.

To play the triangle, a string made of gut suspends it from the top curve, and a metal beater strikes it either on the inside or outside.

When we strike the triangle, it produces a ringing sound. We can change the sound of the triangle by using beaters of varying sizes and thicknesses.

The triangle is considered an instrument of indefinite pitch, producing multiple overtones when struck with the right beater.

By holding the beater inside the triangle and moving it rapidly back and forth, a tremolo effect can be created.

Triangles come in various sizes, and each size produces a different pitch when played.

As one of the smaller percussion instruments in an orchestra, the triangle originated in Europe during the late Middle Ages.

In its earlier forms, it often had several metal rings attached that would jingle when struck.

It eventually became a permanent part of the orchestra in the 18th century.
