after all these years no one has explained to me just what the differences are in mouthpieces.

I know its all about various shapes but...

Rim width affects ____________

Rim shape affects ____________

Bowl depth affects ____________

Bowl shape affects ____________

etc. Can any one sum it up for me?

Thanks!

These can all be found by reading TH. The best way to search is by entering something like the following examples in Google.

site:trumpetherald.com ~rim width

site:trumpetherald.com ~rim shape

etc...

Here are a few links with answers, I'll come back and edit this comment with my takes.

https://www.dansr.com/wick/resources/a-beginners-guide-to-mouthpiece-anatomy

http://www.mouthpieceexpress.com/specshub/anatomy.html

EDIT:

Rim width: more = helps with endurance / less = more precision, more flexibility

Rim shape: more rounded = more precision, more flexibility / more flat = helps with endurance by easing blood flow

Adding alpha angle as it concerns both the rim and cup: higher alpha angle = helps with endurance particularly in the high register, gives lips "padding", adds "edge" / lower alpha angle = keeps embouchure from bottoming out, more "chop room", cleaner articulation

Cup depth: more = darker sound, easier low range / less = brighter sound, easier high register

Cup shape: more C = slows air down, rounds sound, cleaner articulation / more V = speeds air up, directs sound and adds "edge", easier high register

These are very general notions and shouldn't be considered rules. What makes a mouthpiece is the combination of all parts. Other important considerations include the throat entrance, throat, blank design, backbore, and the gap between the mouthpiece and leadpipe. I could add information on those except backbores because they honestly are their own enigma and I'm not as confident with characterizing the different shapes. Also note that terms and even measurements differ between brands adding to the ambiguity. Last time I checked the website was down for me but check out the GR mouthpiece website. They have a whole "school" that quantifies every aspect of the mouthpiece in a more objective way.

If anyone has something they think I should add to this list or see something incorrect please let me know.
