since I my self is an autodidact perhaps someone with more professional fundations would care to help.
I'm currently doing a little home-study in baroque music and wondered if there was any general form of musical structure at the time? I'm aware that the sonata form was used in later periods, but before then was there any at all? Or did everybody experimented untill someone came up with the sonata form? Take a concerto by Bach as an example, what was the common layout?
