Shaking a high trumpet note?
It's called a lip trill. You basically alternate between two partials - the place where the notes are slotted (a little hard to explain but if you play you know what I mean). It's like a trill without moving the valves. Like if you were to alternate between a c and an e - both open fingerings - just go back and forth really fast. Sounds easy doesn't it - it's not.





Little known fact - the higher you get the closer the partials are making it easier to move between them without the valves (at some point in the higher register the valves are almost unnecessary). But you have to be able to play in that range in the first place. And because they're so close together it takes a lot more control.





How do they do it? Lots and lots of practice. You can find drills for lip trills and slurs in just about any intermediate to advanced method book.





Or you can just shake the horn (which a lot of inexperienced trumpeters do). But do it too much and you'll end up with swollen and bleeding lips!
