I think there are different fields of musicology. I'm sure many are musicians but those who focus on how music differs with cultures and it's historical influence may not all be musicians. There's a difference between being a musician and someone who plays piano every now and then.
I'm actually debating musicologist with the instructor, lol. (that came after this post - previously he'd only asked me to clarify)
I went to my first concert last night, it was called Strike with Jeffery Meyer on Piano and Paul Vaillancourt on Percussion.
Quite interesting!! It wasn't like any music I'd ever heard before!! lol But the instructor said it qualifies as Classical Music. I took pages and pages of notes but have no idea how to describe what I heard! Other than saying the pianist reached in and plucked the piano wires, at times. lol
It's certainly going to be an interesting semester.
