Free online music tools
Everything around your practice in one place: keep time with the metronome, tune up, practise riyaz over a tanpura, transpose chords, find the key of a song, explore the circle of fifths, train your ear, learn to read notes and test your vocal range.
Every tool runs in your browser for free, with no download and no account. The metronome, tuner and scale finder are also built into the Music Tools bar next to most instruments.
Practise and keep time
- Metronome: a steady click from 40 to 220 BPM with accented downbeats, four metres and tap tempo
- Tuner: a chromatic microphone tuner that shows the note, its frequency and how many cents sharp or flat you are
- Tap tempo: tap along to any song to find its BPM, with the space bar or a tap
- Tanpura drone: an electronic tanpura on any Sa, tuned to Pa, Ma or Ni, for riyaz and raga practice
- BPM calculator: delay times in milliseconds for every note value at any tempo, and song length from bars
Theory and songwriting
- Scales and chords: the notes of 12 scales and 10 chord types in every key, with a button to hear them
- Circle of fifths: an interactive circle of fifths with key signatures, relative minors and the chords in every key
- Key finder: tap the chords of a song and see which key it is most likely in, with the chords that fit
- Chord transposer: paste a chord sheet, move it to any key and get capo positions with easy guitar shapes
Ear and voice training
- Ear trainer: hear two notes and name the interval, from beginner to all twelve intervals, with a running score
- Tone generator: a steady test tone from 20 Hz to 2 kHz in sine, triangle, square or sawtooth waves
- Note reading: name notes on the treble and bass clef, in letters, solfège or sargam, with a score and streak
