The CFA scholarships, to my knowledge, are for students MAJORING in that college (music, art, drama). Music student scholarships are for students majoring in music and are based on the strength of the audition. Ditto for drama majors. Art majors submit a portfolio.
These scholarships are NOT for non-majors.
If you are planning to be a music major, check out the music department section in the College of Fine Arts. I think you'll find the info you are looking for there.
If not, call the music admissions folks in the CFA. They are VERY friendly and helpful.
DS is a BU music grad. He had a $10,000 a year performance award from 2003 to 2007. We were told at the time that his was a generous award. Don't know if that's true or not
