I am getting my braces off this november, so I figure one thing I can work on now, that SHOULDN'T be affected after my braces come off, is my tonguing. I've actually always kinda, well, sucked at it. I can never get my fingers and tongue to line up perfectly, and when they do, my tonguing is either messy or too pecky, IMHO. I always feel like my tonguing holds me back. Its not, at all, horrible. Its pretty good, but its not up to par with the rest of my playing. What are the best tonguing exercises you guys know of?
