One thing that I've noticed about the trumpet is that the sound from player to player seems to vary a lot more than other instruments. I've noticed that over time, there have been four basic sound concepts. One is the standard concert hall sound concept of a full projecting tone, which is used by every classical trumpet player with few exceptions. Another is the bright brassy sound typically found in mariachi bands. The last two are from jazz. One sound concept is that of a fatter, more bulbous tone, and the other is of a more character-like personal sound with high overtones throughout. For example, the fatter tone: YouTube - After You've Gone- James P. Johnson‏ the character-like tone: YouTube - Roy Eldridge - After You've Gone‏ Though the concert sound, mariachi sound, and fat jazz sound prevail, I've yet to find a recording after the 50s that embraces the remaining sound concept. Why? Does anyone have counterexamples?
