Fever Pitch by Heidi Cullinan

Sometimes you have to play love by ear.

Aaron Seavers is a pathetic mess, and he knows it. He lives in terror of incurring his father's wrath and disappointing his mother, and he can't stop dithering about where to go to college--with fall term only weeks away. Ditched by a friend at a miserable summer farewell party, all he can do is get drunk in the laundry room and regret he was ever born. Until a geeky-cute classmate lifts his spirits, leaving him confident of two things: his sexual orientation, and where he's headed to school.
Giles Mulder can't wait to get the hell out of Oak Grove, Minnesota, and off to college, where he plans to play his violin and figure out what he wants to be when he grows up. But when Aaron appears on campus, memories of hometown hazing threaten what he'd hoped would be his haven. As the semester wears on, their attraction crescendos from double-cautious to a rich, swelling chord. But if more than one set of controlling parents have their way, the music of their love could come to a shattering end.

Warning: Contains showmances, bad parenting, Walter Lucas, and a cappella.
