You probably have one in your bathroom drawer right now. It's plastic, maybe a bit dusty, and costs about two bucks at the local drugstore. Most people see a grooming tool, but if you’re a musician—or just a kid with too much time on a rainy Sunday—you see the potential for a kazoo-style instrument that might be made with a comb.
It’s the ultimate "MacGyver" move of the music world.
The Science of the Hum
Why does it even work? It’s not magic, though it sounds like a swarm of very rhythmic bees. When you place a piece of thin paper over the teeth of a comb and hum against it, you are creating a mirliton. That’s the technical term. Essentially, you are building a vibrating membrane instrument. Your voice provides the initial sound waves, and the paper—usually tissue or wax paper—acts as a resonator. It vibrates against the plastic teeth, adding that gritty, buzzing timbre we associate with early jazz and jug bands.
Honestly, it’s physics in its most lo-fi form.
The tension matters more than you’d think. If you wrap the paper too tight, it won't move. If it's too loose, it just flaps around like a wet napkin. You need that sweet spot where the air pressure from your lungs forces the paper to dance against the comb's spine.
Why Wax Paper is the Secret Ingredient
If you’ve ever tried this with a standard sheet of printer paper, you likely failed. It’s too heavy. The fibers are too dense to react to the relatively weak vibrations of a human hum. Professional "comb-players"—and yes, they exist in the folk circuit—swear by Reynolds wax paper or even the crinkly plastic from a cigarette pack.
The thinness is the key.
Some people use tracing paper, which offers a slightly more "refined" buzz, if you can call a comb-kazoo refined. You’ve got to hold the comb lightly. If your fingers dampen the paper, the sound dies instantly. It’s a delicate balance between your grip and your breath.

From the Back Porch to the Big Stage
It’s easy to dismiss an instrument that might be made with a comb as a toy. But that ignores a massive chunk of American music history. During the Great Depression, people couldn't exactly run out and buy a Gibson mandolin. They made do. This led to the rise of "spasm bands" and jug bands in New Orleans and the Appalachian mountains.
These musicians weren't joking.
They were playing complex blues progressions and syncopated rags. The comb and paper served as the "brass section." When played with enough skill, a comb can mimic a muted trumpet or a soprano saxophone. It’s about the "vocalizing"—you aren't just blowing air; you are singing syllables like "doo," "who," or "brrr" into the device.
Famous Moments in Buzzing History
Did you know the Beatles actually used a version of this? On "Lovely Rita," the band used combs and EMI tissue paper to create that strange, buzzing percussive sound during the middle eight. It wasn't a synthesizer. It was just Paul, John, and George humming into their grooming kits.
It’s a testament to the idea that gear doesn't matter as much as creativity.
Then you have the legendary Red Onion Jazz Babies. In the 1920s, the "kazoo" sound was a staple of the jazz age. While many used metal kazoos, the DIY comb version was the "street" version of the same phenomenon. It allowed anyone with a pocket comb to join the jam session.
How to Build the Perfect Comb Kazoo
If you want to try this, don't just grab any old comb. You want a pocket comb with fine teeth. The wide-tooth "detangler" combs don't provide enough contact points for the paper, resulting in a weak, disappointing rattle.

- Find your paper. Wax paper is king. Tissue paper works but gets soggy from your breath pretty fast.
- Cut a strip. It should be about the length of the comb and twice as wide.
- Fold it over. Drape the paper over the teeth so it covers both sides.
- The Grip. Hold the comb at the ends with your index fingers and thumbs. Don't touch the paper!
- The Technique. Press your lips against the paper-covered teeth. Do not blow. Hum. Say the word "doooo" into the comb.
If you feel your lips tingling, you're doing it right.
The "Soggy Paper" Problem
One thing no one tells you about playing an instrument that might be made with a comb is the moisture factor. Since you are humming directly into paper, condensation builds up. Within ten minutes, your "instrument" is a literal soggy mess.
Old-school players would actually have a stack of pre-cut papers ready to go. They’d swap them out between songs like a guitarist changing a broken string. It’s a messy, cheap, and surprisingly expressive way to make music.
Beyond the Comb: The Mirliton Family
The comb-and-paper setup is just the DIY cousin of a much larger family of instruments. The African mirliton or "onion flute" has been around for centuries. In many cultures, these instruments were used to distort the human voice for ritualistic purposes, making the singer sound like a spirit or an animal.
When you play a comb, you're tapping into a primitive desire to alter the human voice.
It’s not just a gag. It’s a way to turn the most intimate instrument we have—our vocal cords—into something mechanical. It’s a bridge between the body and the machine.
Technical Nuances You Probably Didn't Consider
The pitch of the sound is determined entirely by your voice, but the texture is determined by the comb. A plastic comb gives a brighter, shriller buzz. A bone or wooden comb (if you can find one) provides a warmer, more resonant tone.

Even the spacing of the teeth changes the "frequency response."
Close-knit teeth create a higher-order harmonic distortion. This makes the sound "cleaner" in a strange way. If the teeth are further apart, the paper has more room to flap, which creates a lower-quality, grittier sound. Most players prefer the fine-tooth side of the comb for maximum vibration.
Why We Still Care About DIY Instruments
In an era of $500 VST plugins and AI-generated symphonies, there is something deeply grounding about a instrument that might be made with a comb. It’s honest. It’s tactile. You can’t "autotune" a comb and paper.
It requires a certain level of "mouth feel" and breath control that a computer can't replicate.
It’s also a great equalizer. A kid in a bedroom can produce the same "lead" sound as a professional musician using the same tools. It strips away the elitism often found in music theory and high-end gear culture. If you can hum a tune, you can play the comb.
Practical Next Steps for the Aspiring Comb-ist
If you're serious about mastering this lo-fi craft, don't stop at just humming "Mary Had a Little Lamb." Try these specific steps to improve your "tone":
- Experiment with different papers. Try parchment paper, cellophane, and different weights of tissue to see how the "timbre" shifts.
- Practice vocalizing. Instead of a flat hum, try "growling" into the comb (a common technique for blues harmonica players). This adds a layer of gravel to the sound.
- Record yourself. Use your phone to record a comb track over a basic guitar strum. You’ll be surprised at how well it cuts through the mix.
- Check the comb material. Avoid combs with sharp or jagged "mold lines" on the plastic, as these can tear the paper. Sand them down if you have to.
The humble comb proves that music isn't about how much you spend at the guitar shop. It's about finding the vibration in the everyday objects around you. Grab a piece of wax paper, find your favorite comb, and start humming. You’re joining a century-old tradition of making something out of nothing.
Actionable Insights:
- For Educators: Use the comb-and-paper method to teach children about sound waves and frequency. It's a visual and tactile way to explain how membranes work.
- For Music Producers: Next time you need a "weird" lead synth sound, try recording a comb kazoo and running it through a distortion pedal or a heavy reverb. The organic jitter of the paper creates a texture that digital oscillators often lack.
- For Hobbyists: Keep a small strip of wax paper in your wallet. You never know when a spontaneous jam session might need a "brass" section.
