Classic.

....It depends... which style do you mean? I am not much of a fan of earlier classical works, i just don't connect with most of it.

20th century composition... Crazy shit. Check out 'Bela Bartok'... There is a peice that he wrote, i THINK it is called 'Six dances in bulgarian rhythm - Mikrocosmos' or something similar. This peice is crazy, i have never heard anything like it.
