Vol. IMusic theory made for musicians who play
A complete system for understanding what you play: books built on real songs, exercises with audio, and reference material to keep right next to your instrument.
§ 01Who's behind it
I started out like almost everyone: playing songs from memory without understanding why they worked. When I wanted to study theory, every book I found was written for the conservatory, not for someone holding an electric guitar.
After more than twenty years as a musician, composer and producer, I wrote the books I wish I'd had: theory made for musicians who play, explained with real songs, audio and fully worked-out exercises.
— Damián Calle
§ 02The method
Every piece has a job. Together, they get what you learn onto your instrument, and keep it there.
