Harmony: Music Trainer

Train your ear, read notes on the staff, then play them back on piano, mic, or MIDI. Notes, intervals, scales, chords—progress at your own pace.

Unlock the musician in you with Harmony.

Whether you're a beginner or a seasoned player, Harmony trains you to recognize, read, and play music. Four domains, one method: theory becomes a game of focused exercises you tune to your level.

The 4 domains • Notes — spot and place every note. • Intervals — measure the distance between two pitches. • Scales — major, minor, modes, and more. • Chords — from triads to extended chords, inversions included.

Three ways to train • By sight — read the note straight off the staff (treble or bass clef, key signatures, ledger lines). • By ear — hear a note, interval, or chord, then identify it. • By playing — play the target back on an interactive piano.

Play your way • By touch, on the virtual keyboard. • By microphone, singing or with your instrument. • By MIDI, plugging in your keyboard (USB or Bluetooth).

Why Harmony? • Tailored — pick the concepts, question formats, and difficulty. • Distraction-free — a clean interface built for focus. • Offline — everything works without a connection. • Multilingual — English, French, Spanish, and three note notations (Do-Re-Mi, C-D-E, German notation).

Harmony is just getting started. We improve it every day to build the most complete training companion, from theory basics to a trained ear.

Happy practicing!
