[jazzman1945]

Using conventional mouthpieces contradicts the idea to enhance the expressive possibilities of melodca : it’s like two communicating vessels with a subtle transition tube, rigid or flexible in between. What’s good for gas or liquids, not suitable for the transmission of the subtle nuances of articulation. The one who tried to talk with a pipe in the middle of mouth is familiar with this. It seems that for this purpose the most appropriate form of the mouthpiece- like short respirator or inner side of short curved harp tightly adjoining to the lips from outside.

Up to now I have not found anyone who is willing to make this.
