In the classical period, music was no longer dominant.

I think religious or spiritual type songs.

Classical music was a big shift, even in the "New World" and people in the new worlds had a lot of different religions and gospels, and there are many recorded songs before classical music, before 1775, and these were the songs, mainly, so they weren't dominant.

The answer is a : varying the size of objects or subjects, so that some are smaller than others and the illusion of depth is created.hope this : )
