PlayTheory: Learn Music Theory
Learn to play? Play to learn.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Don't learn to play. Play to learn. Every lesson asks you to play real notes on the built-in piano, so music theory ends up in your hands, not just your head.
Music theory finally makes sense when you play it.
PlayTheory teaches music theory hands-on. Instead of reading about a chord, you play it. Almost every step asks you to press the right notes on the piano at the bottom of the screen, and only moves on when you get it right. That is how the ideas stick.
WHAT YOU LEARN
118 lessons in eight modules that build on each other:
• Keyboard basics: find every note, sharps and flats
• Intervals: the distances that make up all music
• Keys and scales: major, minor and how they are built
• Chords: triads, sevenths and how to name any chord
• Chord progressions: why songs move the way they do
• Reading music: notes on the staff, treble and bass clef
• Rhythm and groove: counting, note values, feel
• The circle of fifths: the map that ties it all together
HOW IT WORKS
• Learn by playing: every concept goes straight into your fingers
• Short steps with instant feedback, so you always know where you stand
• Hear everything: tap any chord, scale or interval to hear it
• Practice sessions to keep what you learned fresh
• Recitals at the end of each module to prove what you know
