@Dale-Proctor said in Spit Building up in MP:
Modern long shank and modern short shank cornet mouthpieces have the same shank taper and should have the same insertion depth. I don’t know why they shouldn’t interchange with good results as well as any other mouthpieces do. Some mouthpieces work with a given cornet, while others don’t, regardless of the shank length.
Bach and Yahama have different tapers that I just noticed. Bacg goes into the shank further. Not arguing with you Dale. The short and long shank yamaha go into the shank the same distance.
The Yahama is close to an old Conn Wonder I have but not exact.
So I guess (as Fluglegirl said) that the Yahama doesn't belong into my Bach.
