How to choose the BEST RIM DIAMETER on Trumpet (it's easier than you think)

Amazing information! I always wanted to know how to have a more precisely idea of how much a mouthpiece it's for me or not

It help, thanks👍

This clarified a few things for me. I'm not really sure what my rim size should be as always played with a lot of pressure due to the flat perfect teeth. I'm trying to get back into playing at home and Jason your videos are a great tool. Thank you Jason for providing such useful advice.

This is great information! I’m a complete mouthpiece novice so videos like this are really good. Thanks

Very helpful and informative. Thank you

Thank you Jason for the drawings. I think Im starting to understand the rim diameter size thing better. Lynn Nickelson says most players play on diameters to big for them. I believe this to be true. I with consider this information for my next harrelson rim.

This helped so much!!! I picked up my crappy horn I rented from my school to test this out right away!

good afternoon

SCIENCE! Thank you for breaking this down into easy to understand format.

Thank you!

So when playing a G scale down to the low G, what is the sound of a "too small" diameter? I assume it is an airy, fuzzy sound where the power and clarity disappear. This assumes no / minimal lip manipulation to "get the low notes out". Am I right?

I find I only get a big, clear low G on my Curry 1 1/4C. I guess that is my size then.

Free me from mouthpiece madness . I need a your mouthpiece so I can switch out pieces

Great info Jason I’m 68 and a comeback player.I love that Bach 5V you tested . Also like the 3 c ,7c MV. ,and the Bach artisan 1C . Bobby Shew . I’m all over the place but I guess the 7c brings back lip memory. I love your concept of Septra Tone cause the throat and cup can be customized

Hey, does anyone know the name of the excerpt in the intro? It sounds like something by Rouse or Shostakovich but i cant quite remember.

Very informative Mr. Harrelson!

Right on the money 💰

I'm afraid this while very well presented was not a help to me. The rest of the planet uses metric units.

Tremendo , muy bueno...

what are the cons if playing a oversize rim mouthpiece?

I want a 15 mm rim size because of my very thin adult lips . What number is this
