Very cool @CowboyNQ ! Do you find it easier playing it with short mouthpiece?
Firstly, thanks!
I find it easier in the sense that I feel I have more immediacy over my breath control, but then I find it more difficult as my close up eyesight is failing me as I move into my late 40's, so I can't really see the keys that well.
I'm still only really learning how to play the thing and I'm far from a virtuoso - but I don't really think it matters whether or not you use the hose or the short mouthpiece - I think whatever makes you feel comfortable.
