Music theory provides a framework for musicians to analyze, understand, and create music. It helps musicians communicate ideas, interpret compositions, and develop their own musical style. While it involves learning rules and conventions, it also allows for creativity and innovation within those guidelines. It encompasses various aspects such as the structure of musical compositions, the elements that makeup music (like rhythm, harmony, melody, and form), the notation systems used to write music down, and the principles behind how music is created, performed, and understood.
Taking one-on-one theory lessons can help you write your own music, understand your pieces better, or work in styles like jazz or blues that bend the conventional rules of music.
