I'll be grateful for advice on how to control longer trompette buzzes, where I am uncertain how far to go, and where to stop. ....Sounds as if I'm in need of agony aunt advice here
In order to achieve the prolonged buzz, I think you call it the coup de bras, the wheel has to go faster for longer, which necessarily means arriving in a different place from where you'd be with no buzz.
So if, for a simple example, I want to play in 4/4 the rhythm 1 2 3zzzzz 1 2 3zzzzzz so that the long buzz starts at 3, goes through 4, and ends just before the 1 comes again, I can see different possibilities:
a) Have the ideal tirante setting so that magically I can achieve staccato buzzes but also the longer buzz without arriving in a different place - Hmmm, not sure how the physics of this work;
b) slightly compress the positions of 2 & 3 so I've got a bit more space for the longer buzz and still arrive at 1 in the right position;
c) make the buzz take the wheel further than usual, therefore re-positioning 1 next time. Which seems counter-intuitive
All this without changing the speed of the music.
And when I want a longer buzz still, the problem is of course magnified.
I don't possess any DVD tutorials... perhaps there's my answer... but have looked closely at various Youtube presentations, including the pretty thorough tutorial Neil recommends on his website.
Players seem to vary a lot. Some seem to achieve the magic (a) option of not ending up in strange positions, others take the (c) option to extremes and produce great sudden accelerations and decelerations of the wheel. And I find it almost impossible when viewing at speed to analyse just what's going on.
The online tutorial I mentioned does explain how it's important to be able to start and stop just as you need, but when he incorporates various techniques into a piece of music, he suddenly speeds his tempo up at the point where he starts using longer buzzes.
If you've read this far, and worked out what I'm trying to say, thanks for your patience. If you can offer useful advice, thanks even more
