Free browser tools for guitarists
A tuner, a metronome, and every chord you are likely to need — all running in the page, with nothing to install and no account required.
Guitar tuner
Chromatic and preset tunings for guitar, bass and ukulele, read straight from your microphone. The audio is analysed in the page and never uploaded.
Metronome
Tap a tempo or dial one in, with accented downbeats. Scheduled through the Web Audio clock, so it stays even while the rest of the page is busy.
Chord library
168 chords with playable fingerings for guitar and ukulele and note layouts for piano, generated from theory and ranked easiest first.
Automatic chord charts
The signed-in half of HearChord analyses a recording and writes out its chords with timings — a scrollable chart you can play along to, correct by hand, transpose, and split into isolated instrument stems to practise against. It runs the same model as the Android app this was ported from.
