Of course there are committees. They just aren't called that.

How else could academics and producers have eliminated all melody and harmony in the course of the 20th Century?

The trend started with 'serious' (symphonic and chamber) music. Instead of melody, we have one note after another. Instead of harmony, we have notes played at the same time for no particular reason. Instead of rhythm, we have a buried beat. Have to have one somehow, so people end at the same time.

Now rock, jazz and country even follow the same rules. Listen to modern country. Do you ever hear a melody? No.
