## What is Learn Music Theory?

A music theory workbook you can hear and play.

Learn how music works through short, interactive lessons: hear each idea, see it on the staff, and try it yourself. Start with your first notes and keep going all the way to jazz harmony.

17 UNITS, 66 LESSONS
• Go from your first notes through scales, intervals, chords, harmony, modes, voice leading, jazz harmony, and modulation.
• Practice each idea as you learn it, with a checkpoint at the end of every unit.
• Take a placement assessment to skip what you already know, or jump to any lesson.

INTERACTIVE CIRCLE OF FIFTHS
• See every major key and relative minor, with sharps and flats.
• Hear the chords of any key and see how they relate.
• Find closely related keys and understand how music moves between them.

EAR TRAINING AND PRACTICE
• Train your ear with intervals, chords, and progressions.
• Read notes on the treble and bass clef, and tap rhythms.
• Revisit skills with spaced repetition.
• Set an optional daily reminder at the time that suits you.

10 INTERACTIVE TOOLS
• Explore scales and modes.
• Build chords and see them on the staff, keyboard, and fretboard.
• Experiment with chord progressions, rhythm, and a metronome.

FOR YOUR INSTRUMENT
