My husband and I are in the process of petitioning our daughter’s HS to allow her to take music theory in lieu of taking Trigonometry. She has aspirations of studying for a BFA in Musical Theatre when she attends college. Music theory would be so much more useful to her choice of career than would trig. I have taken the time to apply each and every Common Core Math Standard to a topic which would be taught in the Music Theory Class. My question, has anyone else thought of doing this? Were you successful? We are confident we can make a case for this and are seeking other musicians opinions.
