Bach is the epitome of composing. His methods are the only way. Sure, he's good, but there lots of other ways to sound good, and his was only one way to sound good in the 1700s. Music learned outside of school is lesser. It's not, it's just different, and much more relevant to how music is made in society in general. Band is everything. It's not. It only really exists in schools and the military, so why would you think that? And community bands only exist because they exist in schools. Classical is a higher form of music. Nope, it's mostly just old. And prescribing classical theory to other musics is inappropriate. Popular musicians aren't real musicians. In a lot of ways they are actually better musicians in the deepest sense of the word. They all tend to be able to read some form of notation, improvise, compose, and learn by ear with relative ease.
