You're conflating two things here re: classical music. There's classical music, the genre, which includes the Classical Period as well as The Baroque, Romantic, and Modern periods. Admittedly, this is really confusing, and it'd make a lot more sense to call one of those "classical" things something else, but I'm not in charge of naming things (any more).
