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 โ€ข Notes โ€” spot and place every note. โ€ข Intervals โ€” measure the distance between two pitches. โ€ข Scales โ€” major, minor, modes, and more. โ€ข Chords โ€” from triads to extended chords, inversions included. Three ways to train โ€ข By sight โ€” read the note straight off the staff (treble or bass clef, key signatures, ledger lines). โ€ข By ear โ€” hear a note, interval, or chord, then identify it. โ€ข By playing โ€” play the target back on an interactive piano. Play your way โ€ข By touch, on the virtual keyboard. โ€ข By microphone, singing or with your instrument. โ€ข By MIDI, plugging in your keyboard (USB or Bluetooth). Track your progress โ€ข Short sessions โ€” choose how many questions, and get your precision at the end. โ€ข Clear statistics โ€” your mastery domain by domain, by question type, and by concept. โ€ข Your practice day streak, to keep the rhythm going. Why Harmony? โ€ข Tailored โ€” pick the concepts, question formats, and difficulty. โ€ข Easy to get into โ€” a guided tour shows you the essentials on first launch. โ€ข Distraction-free โ€” a clean interface built for focus. โ€ข On every screen โ€” phone and tablet alike. โ€ข Offline โ€” everything works without a connection. โ€ข Multilingual โ€” 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!

About

Intervalia

Features
Read full description

Intervalia is a musical ear trainer. The app plays two notes and you name the interval between them - from unison to octave, ascending, descending or played together. Real instruments. Intervals are played on a concert grand piano and an acoustic guitar - recordings of real instruments, not a synthesizer. Choose one or more octaves for the interval, or let the app pick. Every answer explained. After you answer, the interval is shown on the staff, on the keyboard or guitar fretboard, and with note names. Listen to the interval again, or tap any key or fret to hear it on its own. 17 levels. The course goes from contrasting intervals to the most similar ones: first ascending, then descending and harmonic. Earn up to three stars on every level. All levels are open from the start. Custom practice. Pick the intervals, direction, instrument and octave you need and practice as long as you like. Intervals you miss more often come up more often. Statistics. Accuracy for every interval and direction shows what comes easily and what needs more work. Made for everyone. The app works with the largest text sizes, VoiceOver, Bold Text and Reduce Motion, in light and dark mode, in portrait and landscape. Available in English and Russian. Honest. Free, no ads, no sign-up โ€” every feature is available from the start. If the app helps you, you can thank the developer with an optional tip; it doesn't unlock anything. The app collects no data.
