I'm a music major (vocal performance), so I obviously listen to loads of art music. I can also read music, and along with singing I play the piano and trumpet.
I think it would be nice to have more discussion of art music (and you used the term just fine, so don't worry
) on this board, it's just difficult to come up with discussion topics I think.
Some of my favorite composers are Mozart, Beethoven, Mahler, Shostakovich, and pretty much any of the Russian crowd, but Rimsky-Korsakov in particular. Of more modern composers, I'm a big fan of John Cage and George Crumb, and pretty much anything that Kornos Quartet plays.
Sadly, I've never seen a live performance of an opera at a professional level. I'm currently in a production of Mozart's <i>The Magic Flute</i> if that counts for anything.
