i can play an instrument (viola) but i dont think its necessary, i think he should be more concearned with saving school music programs in general, having music classes in school had a huge impact on the musical path i have chosen, and i think it has alot of impact on alot of children, i mean you could hand out a flute and a guitar to every kid in the nation, but who is going to teach them?
ill agree with Sick Wid It that being a musician dosnt make you a better producer, hell i saw an autistic kid on tv who could play 15 different instruments as close to perfect as you could possibly play, but could he take that instrument and create an original piece of music? no, could he tell someone else how and when to play it? no. but expanding your knowledge never killed anyone, and some music theory will probably do you good.
i knew a guy who had years of musical schooling, and to be honest with you, he can sit and have a conversation with you all day about theory, but when it comes time to make an original piece, hes instruments collect dust....why? because hes to busy trying to make it how it SHOULD sound instead of the way he WANTS it to sound.
