The man in blue in the middle utilizing the forward jaw with dry lip embouchure setting. A very common setting seen on trumpet players with strong range. I noticed a couple other dry lip players in the mix as well, Chase played with dry lips too though his horn angle was slightly lower than perpendicular to his face, Sometimes it is hard to prove a person is playing with a forward or receded jaw. As the make up and setting of the teeth can mislead the observer. We have a fine classical trumpet player down in my neck of the woods who appears to be blowing with a receded jaw BUT his tone and playing characteristics including great high range much more resemble the forward jaw player. This is because his upper teeth are curved inward and pull his horn angle DOWN. In all other aspects the man is a forward jaw player. Or rather he achieves the inner embouchure characteristics even with his horn angle pointed slightly down from horizontal.
Marvin, You're a know nothing. Are you trying to corner the market on ignorance? There exists a huge shortage of good lead trumpet players, And plenty of those who refuse to examine the reason why. We'll usually see someone like Marvin in this position: discouraging discussion. Marvin is like so many music "educators" I've known: Just a big fat metronome. Worthless to the cause...
Excellent observation. As a trombonist, I don’t know all the ins and outs of that stuff. But it’s always interesting to hear a trumpeters input on this subject.
