Harmony: Music Trainer
Ear training & music theory
Free · Designed for iPad. Not verified for macOS.
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).
Track your progress
• Short sessions — choose how many questions, and get your precision at the end.
• Clear statistics — your mastery domain by domain, by question type, and by concept.
• Your practice day streak, to keep the rhythm going.
Why Harmony?
• Tailored — pick the concepts, question formats, and difficulty.
• Easy to get into — a guided tour shows you the essentials on first launch.
• Distraction-free — a clean interface built for focus.
• On every screen — phone and tablet alike.
• 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!

What's new in version 1.2.1
• Virtual guitar: answer the exercises on a guitar neck instead of the keyboard. Right-handed or left-handed, your choice in the general settings. The feature is in beta, we would love your feedback.
• The harmonymusictrainer.com website is live: the app presentation and the contact form, which you can also reach from the Information tab.
• Fix: scrolling the instrument with your finger no longer plays notes by accident.
• Fix: sound is sent to earphones and Bluetooth headphones again.
Happy practicing!
