seriously though.. all i did was type "trombone slide position chart" into google and got a ton of hits.
if you`re really having that much trouble... get a teacher.. and quick. are you studying in school? or trying on your own?
everybody sucks when the first start out. it takes time. the amount of time depends on you, your practice ethic, and the quality of your instruction. a private teacher will really shorten the learning curve.
