Free · for guitar, keys and anything you play
Tools for players: tune, hear, transpose.
For anyone who plays guitar, keys, bass, a horn or anything else: tune the instrument, train the ear that lets you play by ear, name a note you hear, move the chords to the singer's key, and find chords for a tune. Five steps, in the order a rehearsal needs them.
Mika plays nothing. He runs the night in the app and listens while you tune.
- Is it in tune?Tuner for your instrument
Guitar, bass, ukulele, violin and forty more: pick yours, play one string, read the note and the cents, at A4 = 440 Hz.
mic - Can you hear what you play?Interval ear training
Two notes, name the gap, ten a day, with a song cue for each. Intervals are what lets you play a tune by ear.
ears - What note is that?What note is this?
A kettle, a doorbell, a ringing glass, a note someone hums: the nearest note and how far off, in cents.
mic - Wrong key for the singer?Transpose chords
Type the chords, move them up or down, hear them first. Spelled right for the new key, with a capo hint and presets for B♭ and E♭ instruments.
ears - A tune and no chords?Chords for my melody
Hum the melody for eight seconds: three sets of chords that fit it, played under your line, names to copy.
mic - Then?Brumm, the app
Hum a line over a running track, then play along. The track follows your key.

When to use which
- Before you play
- Tune every time, in the room you'll play in; strings drift with warmth and humidity. Come up to the note from below rather than down to it: a string pulled up holds better.
- When you learn songs by ear
- Ten intervals a day trains the step from hearing to playing. Start with the octave, the fifth and the major third, as the trainer does.
- When a singer joins
- Find their key with the singing key finder, then move your chords there with Transpose. On guitar the capo hint often keeps your shapes.
- When the tune comes first
- Hum it into Chords for my melody: the safe set is the four pop chords in its key, the darker one borrows from the minor.
Numbers players use
- A4 = 440 Hz is the reference most bands and apps tune to; some orchestras use 442, and there is a 432 Hz tuner for those who want it.
- A hundred cents make a semitone; within five counts as in tune on the tuners here.
- A capo on fret 2 raises everything a whole tone: G shapes sound in A.
- B♭ instruments (trumpet, clarinet, tenor sax) read a whole tone above concert pitch, the E♭ alto sax a major sixth above.
What these tools can't tell you
The tuners and the note finder read pitch; they don't judge your playing or your instrument. A very low string or a buzzing note can confuse any tuner: mute the other strings and let one ring. None of this replaces playing with other people.
Making beats rather than playing? The producer tools are next door.
The tuner, What note is this? and Chords for my melody open the microphone on a tap and close it right after; the sound is read in the browser and nothing is kept or sent. The ear trainer and Transpose need no microphone. How the site counts visits.
