Music tools

Tune your instrument, keep time while you practise, or find a track's tempo and key, free in your browser. Get your guitar in tune by ear or by microphone with standard, alternate, and custom tunings, practise to a metronome that holds any time signature and raises the tempo for you as a passage comes together, find your vocal range and voice type by singing, or drop in a track to get its exact BPM or musical key instantly. Nothing you play, sing, or upload ever leaves your device.
