Two years ago, I had no issue double- and triple-tonguing. After a while, however, I seem to have issues playing quickly enough. I suspect that I have gone back to single-tonguing. How can I go back to being able to double-tongue on Trumpet?
Like you, Samuel, I've gotten away from my double-tonguing but found some excellent suggestions on this website:
It seems that building speed slowly, using the mouthpiece only, and using tu-ku (heavying up on the ku's until clear) are the highlights of the advice offered on this site. Best of luck!
Like the other answer, it's a matter of starting off slowly and building up speed when you practice. The technique I find most helpful for double-tonguing is to double-tongue scales in a variety of ways:
- four beats (tu-ku tu-ku) per note
- two beats (tu-ku) per note
- one beat (tu or ku!) per note
I've also found the exercises in Arban's Cornet Method really useful (it's an enormous book full of studies on every technique).
