Instrument Lessons

Pick up an instrument and start playing. Each track is built around topic modules — Posture, Rhythm, Scales, Chords, plus instrument-specific extras — with interactive widgets you can practice on right in the browser.

How It Works

Each lesson is short, focused, and pairs theory with hands-on practice. Manual lessons are checked off when you mark them done; lessons tied to a RITHM game complete automatically when you hit the goal in-game. Sign in to track your progress across devices.

Want music theory too?

The 24-week curriculum teaches the language of music — notes, rhythm, harmony, ear training. The two tracks complement each other: theory makes you understand what you're playing, instrument lessons make you able to play it.
