@ROWUK said in V, V barrel and barrel trumpet mouthpieces:
@stumac I think that a "barrel" backbore would be something like the Schmidt Backbore that Schilke uses as well as certain hyperbolic shapes used by Monette.
Those that get excited about backbores need to keep in mind that the rim, cup, throat, leadpipe and bell are also in the system and that any advantage is very much dependent on the synergy.
A good playing mouthpiece with a standard backbore gets a flat upper register when we change the backbore in this way. Some like that because they play tense and that compensates...
I can't imagine changing backbore is a "quick" solution to any problems. Every part of the mouthpiece affects the other parts of the mouthpiece. Like you said -- it's a system and it has to all be in harmony to truly work well.
I liken it to a bike fit. You can raise or lower your seat, but then you need to adjust the fore & aft position, as well as angle, otherwise the whole system becomes compromised. Not sure I totally agree with that statement about the mouthpiece giving Miles Davis his "dark" sound. I'm pretty sure that sound came from his head first & foremost, and then his trumpet secondary.
