I was wondering if anyone here had any ideas.
For the last ten years I've been trying to sort out my double (and triple) tonguing. Every day I practise various exercises in the Arban book and Groth's book.
I've tried just practising the ka/ga, playing scales on it, exercises and various other things. I can go ta-ka-ta-ka without the trumpet for hours on end.
I can just about double tongue on a single note for a bar or two, if I try changing note it all goes horribly wrong. Sometimes it feels like the ka is blocking the air too much so I try blowing through it more, however, it hasn't really helped at all. It seems to have stumped my teacher as well.
I'm at a stage now where it is a real problem for my playing, excerpts such as the opening to Mahler 5 or Ravel's Piano Concerto are simply impossible.
Any ideas anyone?
