Very interesting. The part where more mass allows for more energy input without breaking up brought up a question. If the inverse holds true about a light weight system being easier to start the tone but easier for it to break up with more input, does a more open mouthpiece and trumpet offset this? So for instance, does the Claude Gordon personal mouthpiece with an open throat and a skeletonized cup area, paired with a Benge light weight but very open horn produce the best of all worlds? |
That gets very complicated. The more open throat (physical openness) allows more actual air to flow. But what we perceive as resistance is actually how much energy we have to put into tone production (not air) in order to achieve a given dynamic at our ears behind the bell. So a horn that responds very lightly due to low inertia will speak easier, achieve that dynamic typically with less effort, and feel "open", but to the audience, it is purely a gain issue, and what you feel/hear may not be what they do. Overall, you may wind up physically working harder to provide added airflow in this scenario even while putting less energy into the embouchure.
Overall, your specific question about greater stability through pairing a minimal mass mouthpiece and large throat with a lightweight trumpet providing additional "head room" before breaking up, the answer would typically be no on the audience side - due to lack of inertia. However, what you perceive as additional dynamic gain due to the construction of the horn and its leak-back characteristics, as well as a biasing of that leak-back spectrum on the high side from all of the aforementioned elements, it might seem that way to the player.
