The answer to this question may be way over my head...lol

I have read that early composers considered this to be true. This question came to mind because of the number of demo songs in BB that are in E flat. Yes I am aware I can change the key.

I can play guitar without issue in any key but E flat is not very common for Pop music. So is this only true in regard to classical music? Whats up with E flat?

Cheers,
