Hi, I've only been playing for a couple of months. I've started to practise tonguing, and I think I'm doing fairly well. I would probably be a little more confident about what I'm doing if I had an instructor. anyway, I've read about those tonguing-techniques were you move you tongue as if you were saying "tah" or "duh", and it works for me. The thing is, however, that I just feel like I'm just moving my tongue. Will it help tonguing speed and tounging in general, if I actually pronounce the "tah"- and "duh"-sound, or isn't it physically possible to do so while you're blowing?
