<p>You can go to grad school in composition - if you have the portfolio and resume to support an application - it needn’t be with a BM in Composition. But you need to have written music, had your music performed or recorded, possibly won awards or attended significant music festivals. Have you applied for any summer programs? My advice would be to wait for grad school - to build up that portfolio and resume now. Bowling Green has a lot of new music events, workshops, concerts, educational outreach - have you contacted anyone there?
You also might have better luck applying to CalArts for an MFA than you did for undergrad. I still think it sounds like the right kind of place for you. There are a number of electroacoustic based composition departments for MFA graduate study - Mills, CalArts, Brown, Bard, RIT, Stanford, Berkeley among others. You should post these questions on the Music Major forum. There are a number of very knowledgable posters about the electronic & electroacoustic composition world.</p>
