This looks like a great approach, mouthpiece-wise. I’ve been thinking that a trumpet or sax style mouthpiece would make it easier to control the instrument.
This version does look like it would be tough to play while standing. Since I use mine in concert, I need a solution that would allow me to hold the instrument in pretty much the position I do now, with the “S” shaped tube, but with a different mouthpiece.
Thanks for daring that. I’m looking forward to seeing what others have come up with in this regard. It’s such a wonderful sounding instrument, but there are a number of design flaws, and the mouthpiece (or lack thereof, really) is one of them.
