Obviously this is my opinion, and I'm sure this has been brought up before, but I need to know. Why is classical music so bad now? There's this kind of horrible post-tonal music around that is just completely awful. It's honestly making me lose hope in composing.
I'm going to go even further and say most COMPOSERS, not just musicians, like classical music from before 1920 MUCH more than music since. I think they just don't want to seem musically stupid, and when they compose this new music, it's very hard for others to poke holes in it. They like this. Say a student composer writes something in the vein of a 19th century composer but with more progressive harmony and their own personal flair. People could potentially shoot holes in this. But by writing this current intellectual garbage, no one can shoot their music down. It can almost always be defended in some way.
I'd wager nearly all (99%) musicians don't want to hear Cage (for example) over Beethoven and they never will. This is the composers fault - it isn't the audience's or the performer's. People like music the most when it is fundamentally about emotion. They don't like it when it's about going against the grain or appealing to some abstract plan or form. We as a community are actively trying to be open to this music and we still don't like it.
I'm losing hope though. What performers and musicians demanded of composers ~100 years ago was so much more human and so much more real than what is at work nowadays. Now composers write one big work a year, and maybe a song cycle or something, and it all sounds like complete crap. They are obsessed with being original. How original was Bach? Think about that question.
Also, look deep in yourself: do you really like music composed in the last 75 years more than say Beethoven or Chopin or Mahler or Bach?
