I need two music compositions to compare and contrast from these Eras (the renaissance, baroque, and classical).

I need two music compositions to compare and contrast from these Eras (the renaissance, baroque, and classical). Both compositions have to be in different eras and can’t be in the same era, for example one has to be from the baroque and the other has to be from the classical. I need help figuring out what’s the easiest compositions to compare and contrast. What two compositions from these eras can I compare and contrast?
