This article explores the bullroarer’s origins, design, cultural significance, and enduring legacy across the globe.
What is a Bullroarer Musical Instrument?
The bullroarer is a flat, elongated piece of wood or bone attached to a long cord or string.
It is one of the earliest known musical instruments, with a history spanning nearly 20,000 years.
This ancient tool, deeply rooted in cultural traditions, is especially revered by the Australian Aborigines, for whom it holds sacred significance.
When swung in a circular motion, the bullroarer produces a distinctive low, whirring, humming, or roaring sound.
This powerful sound is generated by the vibration of the air as the instrument spins, with its pitch and intensity modulating dynamically.
The sound of the bullroarer does more than signal its presence; it revitalizes the atmosphere, infusing it with fresh energy and prana.
Despite its simplicity, the bullroarer serves as more than a mere musical instrument.
It has been used as a tool for long-distance communication, ceremonial purposes, and as a medium for spiritual connection.
To fully experience its mystical power, the bullroarer must be used in an open space and handled with care.
Bullroarers can vary in size, shape, and material depending on the culture that crafts them.
Typically, they measure between 15 to 60 centimeters long and 1.2 to 5 centimeters wide.
Their sound can travel over long distances, making them ideal for signaling during rituals or alerting others in remote areas.
Historical Origins and Evolution of the Bullroarer
The bullroarer is an ancient instrument with a history deeply embedded in ancient cultures across continents and dating back to the Paleolithic period.
Archaeological evidence shows its presence in Ukraine around 18,000 BC and in France around 13,000 BC.
Other findings in Cave paintings and artifacts suggest that early humans used bullroarers for spiritual, practical, and ceremonial purposes.
These findings suggest that early humans utilized the bullroarer for spiritual and practical purposes.
Anthropologist Michael Boyd has documented the bullroarer’s use across Europe, Asia, Africa, Australia, and the Americas.
Its global distribution underscores its universal appeal and adaptability.
In ancient societies, it was often regarded as a sacred tool, used to connect with the divine or communicate over vast distances.
How To Play or Operate the Bullroarer?
The bullroarer’s design is simple yet effective. It consists of a thin bone or wooden slat with a string or cord attached to one end.
The bullroarer is played by rapidly swinging it through the air in a circular motion while holding the free end of its string in a hand.
The instrument produces audible sound waves as the disc spins, winding and unwinding while slicing through the surrounding air.
This process of playing the instrument resulted in a low, droning, and vibrato-like sound that can travel significant distances as the slat cuts through the air.
Unlike vibrating instruments, the Bullroarer’s disc itself does not vibrate. As a result, bullroarers are classified as “non-idiophonic.”
The sound produced depends on several factors, including the speed at which the blade is swung, the length of the string, and the blade’s design.
These elements influence the blade’s rotational rate along its axis, resulting in a continuous sound whose volume and pitch rise, and fall based on the player’s efforts.
Hence, the sound’s pitch and rhythm can be modified by adjusting the speed and length of the string.
Modulation of the Bullroarer Sound
The modulation of the sound depends on several factors:
1. Length of the Cord: A longer cord produces a deeper, more resonant sound.
2. Speed of Rotation: Faster spinning creates higher-pitched tones.
3. Shape and Thickness of the Slat: A thinner or serrated slat can alter the sound’s timbre.
4. Orientation of the Swing: Horizontal or vertical swings affect how the sound propagates.
The low-frequency component of the bullroarer’s sound allows it to travel great distances, even in dense forests or open plains.
To get a sense of the sound a bullroarer makes, listen to audio in the clip above.
For a more adventurous experience, try spinning two bullroarers simultaneously, one in each hand, similar to the poi technique. This can create a striking and dynamic sound.
Health and Safety Tips for Playing or Using a Bullroarer
When using a bullroarer, it’s important to prioritize safety. The instrument is spun with significant force and speed.
While not heavy, its thin edge can cause injury if mishandled.
- Ensure adequate space: Always make sure there’s enough room around you to swing the bullroarer safely.
- Watch for wind conditions: Strong winds can disrupt the sound and may cause the bullroarer to blow back towards you.
- Secure your grip: Hold the string firmly. If it slips, the bullroarer can travel a considerable distance. If in doubt, tie a loop around your wrist for added security.
- Inspect the string and knot: Check the string for signs of wear and ensure the knot attaching it to the bullroarer is secure. Replace worn strings before use.
Getting Started
1. Begin spinning: Swing the bullroarer in a circular motion. It may not sound immediately, as it needs to build up tension and twist in the string.
2. Add twist if needed: If no sound is produced after about 30 seconds, stop and manually add tension. Twist the string by rolling the bullroarer over your hand or along your thigh. Start spinning quickly before the twist is lost.
Tips for Prolonged Use
- Optimal positioning: Swing the bullroarer in a circular motion beside you for easier control. Larger bullroarers may require spinning above your head.
- Maintain distance: Keep the bullroarer at arm’s length, as it will angle toward and away from you as the string twists and untwists.
- Experiment with sound: Adjust the speed, string length, and surrounding acoustics to influence the sound. The presence of wind or other bullroarers nearby can also affect the tone.

The bullroarer is simple in design yet powerful in both its sound and cultural significance.
Not only will you experience the satisfaction of making something with your own hands, but you’ll also learn techniques passed down through generations.
This process is both educational and fun, offering a chance to explore the magic and history of this fascinating instrument.
Let’s get started and craft your own bullroarer!
Tools and Materials Needed:
- Seasoned wood (log or branch, 8″–2′ long)
- Axe, billhook, cleaver, or splitting froe (for splitting)
- Knife or drawknife (for shaping)
- Sandpaper (optional, various grits: 60, 80, 120, 180, 240)
- Hand auger, bow drill, knife tip, or small poker (for making a hole)
- Cord (e.g., hemp string or rawhide)
- Optional: paint, chisel, or hot iron for decoration
Steps to Make a Bullroarer
Once you have gathered all the necessary tools and materials listed above, you’re ready to begin the process of creating your own bullroarer.
Take your time and carefully follow each step outlined below. This is a step-by-step guide to ensure that you craft a well-made, functional, and lasting bullroarer.
By the end of this process, you’ll have a beautifully crafted instrument that you can use and enjoy, knowing that it was made with your own hands.
Whether for practical use or as a piece of art, creating a bullroarer is a rewarding experience that connects you to a long tradition of craftsmanship.
Step 1: Choose Your Wood
Find a well-seasoned log or branch. Look for one at least 8 inches long, up to 2 feet, from a tree that has died standing, or a branch kept off the ground.
If you’re using store-bought timber, be aware that it may lack the same character as natural wood.
For example, you can use a piece of birch wood found by the roadside and cut it to length.
Ash wood is also a great choice due to its attractive grain and durability. Cedar is another beautiful option, but any type of wood will work.
Step 2: Split the Log
Using an axe, billhook, cleaver, or splitting froe, split the log slightly off-center.
Then split it again to create a thin billet of wood from the log’s center.
Aim for a thickness of about 1/3 inch to reduce the amount of carving and sanding needed later. Use caution with sharp tools.
Step 3: Shape the Bullroarer
Trim the billet roughly flat, narrow it, and shape the ends into gentle curves with a knife or drawknife.
The finished bullroarer should measure:
- Length: 6″–2′
- Width: 1″–2 ½”
- Thickness: ¼”–½”
Step 4: Drill a Hole
Make a hole near one end of the bullroarer using a hand auger, bow drill, knife tip, or even burning with a small poker.
The hole must be large enough to thread your chosen cord through.
Ensure you do not split the wood while doing this and be careful to drill the hole properly.
Step 5: Smooth and Decorate (Optional)
- Sanding: Use sandpaper (starting with coarse grit like 60 and working to finer grits such as 240) to smooth the surface.
- Ancient Techniques: For a traditional approach, use dogfish skin or pare it smooth with a knife.
- Decorate: Carve designs into the wood with a knife or chisel, burn patterns with hot iron, or add paint made from soot or natural earth pigments mixed with oil or fat.
Step 6: Attach the Cord
Choose a strong, thin, flexible cord, such as hemp string.
If you’re making your own string, I recommend avoiding a simple two-strand twisted cord, as the twists are likely to unwind. A three-strand plait works much better.
Use strong fibers, such as those from nettles or lime bark, to ensure durability. Your finished cord should be very strong for safety reasons.
To make plaiting or braiding easier, it’s helpful to maintain a bit of tension on the strands.
You can secure the fibers to a place where they can be held firmly while you plait them.
Tie the bullroarer to one end with a secure knot that allows it to spin freely without pulling off-center.
You may also add a wrist loop or attach the other end to a wooden handle for better grip.
Now your bullroarer is ready to use!
Step 7: Test Your Bullroarer
After your bullroarer is ready, it’s time to test your homemade instrument.
Hold the end of the string securely and let the wooden bullroarer hang freely.
Start by giving it an initial spin, then swing it above your head or by your side.
As it gains speed, you’ll hear the characteristic roar—faster swings produce a louder sound!
Thanks to its shape, the bullroarer will continue spinning and roaring after the initial momentum. Enjoy the experience and play safe!
