Salutations fellow musicians in trumpet land!
So as some of you may or may not know (I've made posts about this in the past however I'm not the most popular guy on TM..), my schools' spring musical will be Beauty and the Beast. I'm super excited, as are all of my pit friends and choir friends. I've started listening to the soundtrack to get a sense stylistically and I particularly really enjoy the overture. As of right now there are two trumpets auditioning, me being one of them. The other, is principal in our concert group, however our skills are pretty well matched, and I have an extra year of doing pit than he does, so chair placement could go either way. If I do get first, and I really hope I do for this show, the overture has a very beautiful trumpet solo that I would be playing. Solo linked here, please watch this, as I will be referencing it in my question. The solo starts around the 30 second mark and it's obvious where it ends. When the melody repeats itself a second time (at about the 40 second mark) Neil Balm or Tony Kadleck (I don't know which of them plays it..) soars to a g on top of the staff and uses a very large sounding, very fast vibrato.
My question, how do I practice, develop, and learn to use that kind of vibrato? Currently, I use air vibrato a lot and pull out the lip vibrato when I see fit as well, however, I know even on a good day I can't get a lip vibrato going that fast. Any help/suggestions/practice approaches are greatly appreciated! Thanks!!
