Drum Tuner Online: Snare, Toms, Kick and Timpani
This drum tuner runs in your browser, free, with nothing to install. Pick the drum, set how many tension rods it has and tap lightly with a stick near the edge, in front of each rod. On every tap the tool measures the frequency of the head at that spot, shows it in Hz and as a note, and compares it with the other rods: how many cents it sits above or below the average and whether to tighten or loosen it a little. The hoop diagram numbers the rods in star order and highlights the next one.
How to use it
- Tap Turn on microphone and allow access. Choose the drum and the number of tension rods. Keep the phone 30 to 50 cm (12 to 20 in) from the head, with the other drums quiet.
- In By tension rod, tap lightly with a stick (on a pandeiro, with a fingertip) 2–3 cm (about an inch) from the edge, in front of the highlighted rod. The tool measures it and moves on to the next one in star order.
- Once all rods are measured, each one shows how many cents it is above (+) or below (−) the average. Tighten the low ones, loosen the high ones, always in small turns, and tap again in front of the rod you adjusted. Tap a rod in the diagram to measure that one again.
- When every rod turns green, choose Resonant head, flip the drum and repeat. The bottom line compares the average of both heads.
- In Drum pitch, hit the center: you get the note of each drum and a kit list with the interval to the next drum. On timpani, pick a Target note and adjust until you see ✓.
Help and explanations
Tuning a drum is first of all about even tension across the head: with uneven tension the drum beats against itself, dies quickly and bends in pitch after the hit. The final tuning is a matter of taste, and the tool does not push any note. The Drum pitch mode compares the drums in your kit and shows the interval between toms, and the page also works for pandeiro, Brazilian timbal and timpani. Audio is analyzed on your device; nothing is recorded or uploaded.
How to tune drums in practice: snare, toms and kick
With the new head centered, finger-tighten every tension rod until it touches the hoop: that is your equal starting tension. With the drum key, give each rod half a turn in star order (always across to the opposite rod) until the wrinkles are gone, and press the center with your palm to seat the head; a cracking sound at this point is normal. Then go up a quarter turn at a time, still in star order, until you are close to the sound you want; only then use the tool to even things out. If one spot is high, the usual fix is to back that rod off a little and bring it back up to pitch.
On the snare, switch the snares off while you measure rod by rod: their buzz gets in the way. The snare-side head is thin and usually quite tight, without overdoing it. On toms and floor toms, the resonant head can match the batter, sit a little higher (longer sustain) or a little lower (shorter sound, pitch drops after the hit); one drumhead maker suggests the bottom head about a half step higher, but it is your call. On the kick, many drummers tune just past the point where the wrinkles disappear, for punch more than pitch; measure before you add a pillow or muffler.
Pandeiro, timbal and timpani
The pandeiro, the Brazilian frame drum, has a single head, natural skin or nylon, held by tension rods around the frame. The technique is the same: tighten in a crisscross pattern, a little at a time, and tap near the edge with a fingertip in front of each rod until they match. A natural skin changes with humidity and temperature, so check it before you play. The Brazilian timbal, also single-headed, follows the same process; both are usually tuned high.
On timpani, evening out the rods is what timpanists call clearing the head: the same pitch in front of every tuning screw, otherwise the note rises or falls right after the stroke. With a clear head, the note comes from the pedal. Each drum covers roughly a fifth; orchestration and percussion books give D2 to A2 on the 32", F2 to C3 on the 29", B♭2 to F3 on the 26" and D3 to A3 on the 23", with sources differing by a semitone.
What the tuner measures and what it does not
A drumhead does not vibrate like a string: it has several vibration modes that are not whole-number multiples of each other, and tapping near the edge brings out the higher ones. That is why the frequency in front of a rod is higher than the note you hear at the center. The tool detects the hit from the jump in level, skips the stick attack, analyzes the sound from 40 to 250 ms afterwards and picks the strongest peak in the drum's range, preferring the same peak as the rods already measured.
It does not measure overtone balance, sustain, muffling or the snare wires, nor which tuning suits your style. A noisy room, another drum ringing along and a distant microphone all get in the way; below about 50 Hz some phones pick up very little, which matters for a large kick. If you see "No clear pitch", tap again a bit firmer or move the device closer.
Tips
- Measure each rod twice before touching the key. If the readings differ, the tap changed place or strength: always tap at the same distance from the edge.
- To make the toms sound like a set, many drummers leave intervals of a third or a fourth between them. Hit the center of each one in Drum pitch and read the intervals in the kit list.
- Mute the other head and the neighboring drums with your hand while you measure: they ring along and pull the reading.
- To practice with your tuned kit, use the metronome; to see the head's spectrum, the spectrum analyzer.
Frequently asked questions
Is there a tuner for the pandeiro?
Yes: choose Pandeiro, turn on the microphone and tap near the edge with a fingertip in front of each rod. The tool shows which spots are higher or lower and tells you to tighten or loosen. The final pitch is up to your ear.
How do I tune drums with a tuner?
Seat the head, tighten in star order until you are close to the sound you want and tap 2–3 cm from the edge in front of each rod. Correct the ones that drift from the average with small turns of the key and repeat until all are green; then do the same on the resonant head.
What is the right frequency for a snare or toms?
There is no single right frequency: it depends on the drum size, the heads, the style and your taste. What holds for any tuning is an even head at every rod. If you like a sound, write down the average Hz of each head so you can get back to it.
Do I need a drum tuning app on my phone?
No. This drum tuner runs in the browser on your phone or computer, with no install and no sign-up. Just allow the microphone; the sound is analyzed on the device itself.
Can I use it on an electronic drum kit?
Not really: on an electronic kit the sound comes from the module, and mesh head tension only changes how the stick bounces. Set that tension by feel and change the sound in the module.
Does it work as a timpani tuner?
Yes. In By tension rod you clear the head; then, in Drum pitch, choose the timpano and a target note within its usual range and adjust with the pedal until you see ✓.
