I've been practising double tonguing lately, it goes quite well now, and my teacher said to me that I master double tonguing when I can play this:
MNOZIL BRASS Kill Bill-Green Hornet - YouTube
When I heared it, I was quite stunned, and now I want to be able to do it myself.
I've tried it, but it's not coming along very well, I'll have to look at some other pieces to practise it more (any suggestions?). I thought it might be a challenge to do for some of you guys.
The sheet music is on here: Concertos, Etudes & Duets
