oooooh! I want to be part of this musical!
Annie- Im 13, almost 14 (June) :)
And I don't have much advice for starting oboe. I went from piano to guitar to oboe, and none of those instruments are alike in the way you play them. People say oboe's really hard, but not for me. I guess because clarinetist's are used to one sided reeds, its hard. But seriously, don't let double reeds intimidate you.
Actually, my clarinet friend tried playing my oboe once and she could do it easily- the tone was just not good. She also complained that the reed was vibrating her mouth so much she couldn't play; so I'm assuming that the embrochures are very different.
If you have any oboe related questions now or in the future, I'd be happy to answer them. I've been playing for 3 years, and if I may flatter myself: I don't suck. Too much. :)
