Learning a bit of music history will give you a roadmap. By placing a composer in the time line of the evolution of western music, you will have a scaffold to frame your listening and other learning. When you hear something you like (or don’t like) look at when the composer was working and who they studied under. Then explore a bit about that time period and the artistic aims of the composers of that period. Listen to what you enjoy and to music adjacent (by time and school) to what you enjoy.
