I've been playing oboe for 4 years (in 8th grade) and I want to pick up a sax to play. I'm a girl, 5' 2'', around 90 pounds. I think alto would be better since I'm kinda short, but what do you think? Also, what would be easier to learn over the summer 2012? Would I need to get a private teacher to get up to a high school level, or just a tenor 'how to play' sort of book? Also, since I'm an oboe player, should I learn to play with a double lip?
