Music theory is the study of how music works. It covers the basic elements of music, such as pitch, rhythm, and harmony. It also explains how these elements work together to create a piece of music.
Music theory is a valuable tool for any musician. It can help you understand why a piece of music sounds the way it does, and how you can change it to suit your own taste. It can also help you compose your own music, or simply make your existing repertoire sound better.
There are many different ways to learn music theory. You can take classes, read books, or watch videos. You can also learn by ear, by listening to music and trying to figure out how it works. Whichever method you choose, the important thing is to keep learning and expanding your knowledge.
