Music for the Courts of Nobility is NOT the music we hear today. We hear the major works for the masters, which was commissioned by nobility and religious leaders, the latter which obviously had wide distribution, but the former also was used to appease the "masses" at least the much lesser nobles, merchants, etc. There was little music for the masses at all then.
YOU may want to learn a little about say "Mozart" and what a patronage meant back then. Today's equivalent is employee with a rather defined salary whether for nobleman or religious leader, the definition of "commercial". He eventually struck out on his own .... again commercial ... and then went back to employment. It was called "patronage" back then, as unlike say a blacksmith, there was no inherent value or output you were being paid for, a frivolity so to speak, but absolutely his commercial paid career was making music, complete with the influence of his "patron".
