Learn Western Music Theory, Interactively.
Explore notes, scales, intervals, chords, rhythm and music notation through interactive lessons and playable exercises. Build your musical foundation, hear the concepts in action, and practice as you go.
Pitch
Everything starts with pitch - how notes are named, written, and read. These four lessons give you the vocabulary for all the music that follows.
Notes
Learn the seven natural notes, find Middle C, and hear how octaves and half steps work - on a piano you can play.
Start lesson →The Staff
Learn the five lines and four spaces, read notes upward step by step, and meet ledger lines - with a name-that-note quiz.
Start lesson →Clefs
Treble and bass clefs, the grand staff, and Middle C as the hinge between them - then a clef-switching quiz.
Start lesson →Accidentals
Sharps, flats, naturals, and enharmonics - name every black key, then find them all with labels hidden.
Start lesson →Structure
Once you can name and read notes, you can start combining them. Intervals, chords, scales, and keys are the building blocks of every song you love.
Intervals
Count the distance between notes, hear consonance vs. dissonance, and train your ear to name intervals blind.
Start lesson →Chords
Build triads from root, third, and fifth, hear the four-chords progression, and tell major from minor by ear.
Start lesson →Scales
The W-W-H pattern that builds every major scale, its minor cousin - then build C and G major yourself, key by key.
Start lesson →Keys
Key signatures and a tappable circle of fifths that plays every tonic chord - plus a final exam quiz.
Start lesson →Exercises
Interactive trainers for notes, key signatures, intervals, scales, and chords - on the staff, the piano keyboard, the guitar fretboard, and by ear.
