I just picked up trombone not to long ago in an attempt to teach myself. It's actually been going great.
However, I'm a lefty, so pretty much everything I do is based around the left hand. At a lesson from a friend, he pointed out that I use my left hand for the slide as opposed to my right hand on the slide.
My question is, would that pose any kind of problem? I didn't think it would, and neither did my friend, but I just wanted to get some other opinions.
