Ok, so a while back at an orchestra rehearsal, one of the guys in the section brought a Bach Strad C, just the usual one (I can't think of the exact model number right now). Well, me being the curious one that I am, I asked if I could try it out. First time I've ever played a C trumpet. Hated it. Why? Because, after 9 years of playing the Bb, I have in my mind a pretty good idea of what a certain fingering sounds like. And the C trumpet was just screwing that all up. I couldn't get a good tone, and doing passages was very different indeed. So my question for those of you who switch between the two, and even other keyed trumpets, how do you prepare yourself mentally and physically for the change so that it isn't so awkward?
