I'm a comeback player.. have been working hard for the last few months after about a 25 year hiatus. When I played more (high school and college) I always felt I had a slow tongue. While now, after getting to page #35 in Arbans I'm feeling the same way. I'd like to improve and have been working hard to play those pages at the fastest tempos, but they're sloppy and take a lot of work just to get there. Any help besides just practicing more (which I'm doing)?
