Hey guys, I'm a new member to TH.
Last week I had a GR consultation with Alexa Yates, which was a great experience. When it came down to 2 mouthpieces in the end, it was a G66CX vs a 66CX (Only difference is the rim). The G66CX was the winner on my Bb, though I tried both again in my C trumpet and the other one was better. I ended up only buying the G66CX because as a high school player, I couldn't justify buying 2 mouthpieces at $199 each, and the G66CX worked well enough in the C. My question is this: when playing the 2 mouthpieces against each other in the C trumpet, the 66CX had slightly better articulations with a "pop", which can be attributed to the rim shape, but it also had a much more brilliant sound. The mouthpiece with the G rim was darker. My observations were affirmed by both Ms. Yates and my father. Just out of pure curiosity, how could the G rim change that much about the sound when every other aspect of the mouthpiece (#3 backbore, CX cup, 66 rim series) is the same except for the rounder, wider rim? My only theory is that the extra width of the G rim adds just a tiny bit more mass to the mouthpiece, but that difference seems so insignificant to me. |

Most likely the sound difference has to do with lip engagement. (How your lips protrude into the cup.) Overtime, as you settle into the mouthpiece, you will get that articulation. Good luck!

| I would think it's more likely that the rim itself is the cause - if the rim reduces how much lip protrudes into the cup then the effective cup volume is larger, which would darken the sound a bit... Doesn't need to be a huge difference to be noticeable. |

The G rim doesn't change the lip engagement in any way. What it does change is the lip vibrating surface. There is a test for this.
The difference in the standard GR66 rim and GR G66 rim a little width, the highpoint, and the way the outside radius slopes.
An instant fix would be to take pressure off the top lip. If it works on the Bflat, yet the C seems to be more work or the sound is deadened. Back off pressure on the top lip. The rim was designed to force you to keep pressure off the top lip.

This is Alex Yates. The first thing you need to realize is that C trumpet has less tubing than a Bb trumpet. It is also a completely different blow than Bb. That alone changes many things about engagement between the face, mouthpiece and instrument. Also, you really need to keep pressure off of the top lip (remember, we spoke about you being an 'upstreamer'?) When you take away the tubing for C trumpet, the equation changes and therefore, a mouthpiece that forms a true seal with your face will also change. Does this help clear things up for you a bit?  The mouthpieces are made balancing all 24 parameters. If you change one thing, you change all of the parameters to keep it in balance. The difference may seem insignificant to you now because you are young and inexperienced. As you grow musically and your approach changes, it is majorly significant. You will learn this as you mature as a player. If you are using your Bb mouthpiece on your C trumpet you will be "making it work" and that will cause manipulation and bad habits to develop. The entire process, when done correctly, gives you the feeling of being one with the instrument and no longer causes manipulation. I hope this helps.
