Harmony Theory

What drives us to spend so much of our lives stuck away in our studios? What is it that we're trying so hard to achieve?

String Theory, written by and featuring Guitar World Senior Music Editor Jimmy Brown, is a collection of the first 10 String Theory columns that appeared in Guitar World magazine and their accompanying instructional videos. Over the course of the 10 chapters, Brown presents a "schooled," or "informed," approach to improvisation that's rooted in a jazz mindset, but geared toward rock guitarists looking to expand their theoretical knowledge base and apply practical music theory.

Harmony in Practice explores the main elements of tonal harmony. Students using this book will acquire a secure knowledge of the basics of harmonic practice. Singing, playing and completing the exercises, and studying the music examples, will provide essential experience of the 'tools of the trade'.
