About ChordGrind

What it is

ChordGrind is a free set of practice tools for keyboard and piano players. It drills the things that take the most repetition: chords in every key and inversion, sight-reading chord shapes, shell and rootless voicings, slash chords, accompaniment rhythms, scale fingerings and mode ear training.

How it works

Every trainer runs in your browser. Pick a drill, play along with the metronome or connect a MIDI keyboard for instant feedback, and your sessions are saved on your device — nothing is uploaded, and there is no account to create.

My Plan rotates through all 12 keys on a two-week cycle, and the Dashboard shows which keys and chord types still need work.

Who it is for

Self-taught players, students working through all 12 keys, and anyone who wants their hands to find a chord without thinking about it. It is free and will stay free.
