Understand the music behind every score

Grammar of Music is our new interactive music theory system. Every interval, chord and progression plays as you read, so you train your ear while you learn — and every score you pick up starts to make sense.

• Hear every concept, not just read it
• Chord dictionary, circle of fifths and more
• Guided courses from basics to harmony
