Garage Band Theory

This is the best book I’ve seen on understanding music in a practical, accessible way, with an accompanying website full of free support materials such as audio files, music scores, and a huge variety of songs across genres and instruments. It’s aimed at those who play by ear, back-porch pickers, semi-pros, and pros. I’ve tried learning theory in many ways, from college classes to online courses, but I found the approach of this book the best, and I imagine learning from it for years to come.
