While it’s possible to play jazz guitar without an understanding of music theory, it’s much harder to excel as a musician without it. Music theory provides a foundation for understanding the structure and organization of music, which is essential for creating complex chord progressions, improvising confidently, and composing your own jazz compositions. By taking the time to learn music theory concepts such as chord construction, harmony, and scales, you’ll be well on your way to becoming a master jazz guitarist.
