resonance approach

This thing I call "the resonance approach" may be best understood in contrast.
It all starts with changing partials. As I have written before, there seem to be three basic ways to change partials. To go up, add air, tighten chops, or tune the mouth cavity for the next partial. Please let me know if there are other basic ways!) It is easy to demonstrate this starting from 3rd partial F to 4th partial Bb. A puff of air will take me up. Squeezing my lips will, too. (It's worth trying those right now.) But third, shrinking the mouth cavity can prompt the change.
I think I can hear players of these different styles. Lou McGarrity sounds like an air player. More and more volume up to 12th partial Eb. Stu Williamson when playing trumpet, too. The chop strength player may be represented by the horn player linked on a previous thread where he described how he used to play (how does one find old stuff here?). And I think David Vining may have been that type player beforehand also. I put my old self in that camp, too. It is quite possible to play by adjusting tension for every note and volume, but it is like doing chin-ups all the time. (And I'll bet that chop strength is probably a very common way to play, perhaps the most common.) I suspect in the resonance camp you would have both Fontana and Rosolino, as the sound is there, and the flowing technique that clearly is not work for them seems to point in that direction. On my phone somewhere is a Fontana quartet piece where he plays for a good ten minutes! The only conclusion I can make about that is the guy could not have been working hard. It had to be easy.
Hearing/feeling this resonance can be done with variations on long tones. I suppose one could find the mouth and chops posture(s) that create the most resonance on a pitch with a standard long tone. But tones that change are better. Intervals, scale fragments, arpeggios, all slurred and glissed with no tonguing. Slow, squidging the parts around and listening. The changing pitch forces adjustments to mouth volume, and changing partials is especially valuable to guide the parts toward resonant relationships. When I say "feeling" I mean both the memory of the posture of all the parts that makes for most resonance, but I also mean the very strange tactile feel on the tongue of a vigorously vibrating mouth volume. When that shows up, it is emphatic and bloody obvious.
Hearing the resonance can be greatly improved by using a practice mute or earplugs. It seems to be true that the most vibrant open bell sound is the one that creates the most head noise, and that appears to be when the system of mouth parts is tuned to a partial on the horn. Mutes and plugs help one to focus on the head noise.
The whole point of this is that adjusting the posture of mouth parts for a resonant pitch selects that pitch from all possible pitches the horn can play. It does not make the pitch, it selects it.
