In the course of trying to learn a little bit about the whats, whys, and wheres of C trumpets in order to help me find a C trumpet for my kid, I have read several of this forum's archived C Trumpet threads. I have also read a bunch of other "general" trumpet threads. One question (of no import other than my own curiosity) has arisen: Why don't lead players that strive to play extremely high use C trumpets? (or do they?) I am not implying that "high is it" or that high is the goal for most trumpet players. But, being able to play extremely high leads does seem to be a goal for at least some players at some times. I have read discussions about seeking out thin but "hot" mouthpieces that sizzle out those really high licks. I have read discussions concerning techniques and horn mods that allow super high licks. And I have also read that a C trumpet, naturally, by its design, will play a step higher than a Bb horn. So, why wouldn't a player who wants to play extremely high licks (by ear, I'm assuming) use a C trumpet in order to, by trumpet magic, turn those high Cs into Ds and those high Ds into high Es, and those high Es into high Fs and, well, you get the picture. I mean, who would even know (in the audience, that is). The audience would be amazed at the seemingly effortless stream of unusually high notes coming out of the horn. If a trumpet player spends most of his time in the stratosphere and wants to zoom "to infinity and beyond", why not use a horn that has a built in advantage? Or do they. .
