I also recall when lots of kids were taking trumpet lessons in school - those days are gone forever. Same was true with trombone, which my grandson is learning how to play.

Gary, I don't much disagree with the other statements in your post, but this one is just incorrect. I have seen many middle schools and high schools where there are students learning all the horns and woodwinds and are members of school marching bands, orchestras, jazz bands, etc. etc.
Fortunately, music studies are alive and well in most school systems ...
