It’s common for guitarists to learn by ear, by mimicking their teacher, or from TAB. Players can improvise, write songs, and perform without having a clue about music theory or notation. Some don’t mind staying in the dark about the inner workings of music, and that’s fine. However, many of us get curious about music theory at some point. If that spark strikes you, don’t hesitate to seize the opportunity and start learning. Investing just a little time in the fundamentals can transform the way you see and hear music and open up new avenues for your playing.
