My oboe playing is what paid for my school. There are TONS of scholarships out there for music majors, and then they can make great money teaching private lessons on top of it. I don't know how that would work for art though.
Go ahead and encourage that trombone playing!! Just buy earplugs the first year of learning lol.
Note to self:
If I ever have kids don't introduce them to anyone in texas named meg.
