Learn piano chords, the musical way
Harmonic is a free chord trainer that works like a game and teaches like a musician. You climb a ladder of levels — first triads, then inversions, then fuller voicings — and every exercise is built from chord progressions that real records use, so what you practise is what songs are actually made of.

What it does
Plug in a MIDI keyboard or use your computer keys. The trainer shows you each chord, listens to what you play, and scores your accuracy and timing. A Challenge mode plays chords for you to find by ear, and everything you learn unlocks real songs to play along with.
- Guided levels from first triads to advanced voicings
