Just remembered the whiplash I got from Harlan saying “timpanies” so here’s a little rant about it
Timpani is technically already a plural word. Even though it can be used for just a singular drum (ex. can you move the 29 inch timpani to the left?), the correct word for a singular timpani drum is technically timpano. Even if the orchestral setting that Kayne was in had multiple timpani players, they would probably just be called “timpani.”
Ok rant done I just remember my head WHIPPING to my phone when he said that, and I had to do a little psa for all my non music folks!
