I was doing a search and got very frustrated by overly vague titles. I hope my title has enough info to let future readers know what the thread is about. -------If you want to skip over the next few paragraphs (background) and get to the actual question I have: scroll on down, my friend! ------- I recently purchased a Bb rotary trumpet from George Schlub. It is modeled after the Gansch horn. (for those unfamiliar - it is a vertically set rotary valve trumpet so that one can play with one hand while turning pages, switching mutes, scratching ones head, etc). I have been practicing nightly with this horn using only one mouthpiece working on getting used to it. I have done two big band gigs with it. The first gig left me a little unnerved, but thought I should give it another chance. The second gig was better, but still I had issues with some seemingly simple musical moments. I was finding it difficult to place simple notes. Most particularly second space A and a few others nearby this note. I generally play first, but in this group we do try to keep everyone happy and so sometimes I have 2, 3 or 4th. I was finding that this occurred when I was not playing first. - also... can I blame it on the trumpeter to my right who tends to play quite flat (except when he's knocking out high notes - then he is either in tune or tending to go sharp)? When I practice i have no difficulty with these pitches. (and I generally do a lot of low range drills for finger dexterity, etc.) Is there anything I need to know about air control, slotting, etc. for a rotary that is different from a piston trumpet? thanks in advance for any help in taming this sexy horn!
