i don't understand modern music one bit. i've got a dvd of glenn gould playing stuff by the members of the so-called "vienna school" which is all abstract & weird, & not really musical at all. some people think that stuff is great though, but i can't understand why. i've heard other 20th-century stuff by stravinsky, rimsky-korsakov, prokofiev & others & i don't get it. is can someone explain why it's so interesting?
