In my experience, I think the best method is to start at the present and work my way backwards, so I'd like to start with more recent music. For example, I am spending a lot of time listening to Stravinsky lately, so I'd love to study him. In terms of what kind of art music, I'm really drawn to symphonies as they remind me of philosophical systems, and I'm also drawn to piano music and guitar music as I have a background on those instruments. I'm willing to go anywhere to study, very open to travel but very comfortable at home as well.
