Mastering the CAGED System
New
beginner · Theory
Tommy Gerlach
I often tell my students, the more you learn on the guitar, the more fun the guitar is to play. As a guitarist, being able to pick up the instrument and play freely, anywhere on the neck, is one of the most joyous things in my life. In this course, I want to teach you how to do just that. Make the guitar more fun and help it bring joy to your life. We will dive into understanding the CAGED system, and along the way, dive into basic theory. The goal is to train you to think like a pro by establishing basic theory concepts like, where do scales come from? How do I know what notes are in what chord? How do I target notes in a solo? How do I solo or compose in any key? How do I know what key a song is in? How can I learn a song or lick by ear? Answering all of these questions will allow you to flow freely around the instrument and sound more like an experienced pro.

Learning the fundamentals of guitar theory and applying them to your playing typically takes around 80-120 hours. If you practice 2 hours per week, that's about 1 year or 5 - 7 months if you practice for 30 minutes daily. For most people, the hardest part of learning guitar theory is understanding how scales, chords, and progressions work together to create music. To effectively learn guitar theory, finding a great teacher is crucial. A knowledgeable instructor can break down complex concepts into digestible lessons, provide practical examples, and help you apply theory to your playing, which is far more efficient and effective than self-guided learning.
