I'm 5'4", in high school, and I play(ed) bari sax. I was doubling for pit orchestra, so I'm not currently still playing it(school instrument not mine), but it was awesome fun. my friends laughed at me cause it was about as tall as i was when i was sitting with it though. I have and occasionally play an alto, but I don't really like it that much.

granted I'm a bass clarinet player primarily, so I'm all for the lows
