My husband and I were both music majors (voice). Neither one of us really worked in the field, though, mainly due to the low pay and job instability, especially once we had mouths to feed. Still, I earned my degree due to my love of music, so it wasn’t in vain.
I had somewhat of a similar career trek. I received my BA in Musicology, which for all practical purposes was a "ticket to graduate school". I wound up working for a while in Special Education, then in insurance, took an aptitude test and found out that musicians make excellent computer programmers (who knew they use the same part of the brain?). One thing led to another and I became a software engineer, and eventually that graduate degree, which was an MBA.
Long story short, I'm still extremely grateful for that undergraduate degree in Music lo those many years ago. I can still listen to a few bars of a classical piece of music and recognize the composer as well as the piece (I tend to be partial to the late Romantic, 20th century era French composers).
