Hello. I'm a video game composer for small games, usually for kids. My compositions are mainly easy melodies and not a lot of harmonies, counterpoint, and instrumentation involved. I've never been in a college level music class before. I can create these compositions because I'm a guitar improviser. But I want to up my game. I have sheet music of John Williams' compositions on various films. However, I don't know how to study them. I don't know what I should be looking at to understand the composition more. If hypothetically I have 5 hours a day for music what should I do to improve, understand another composer's music, and hopefully be able to create my own music incorporating bits of what I learned from other composers?
Thank you for reading this. I appreciate all the help.
