For the last few months, now and then when I've been working on double-tonguing, it'll flip into overdrive for a couple of beats and then fizzle out, moreorless the instant I start wondering what I'm doing that's getting it to work. Today was the first day I felt I'd started to get some sort of control over it. One key seems to be to relax pretty well totally and let my mind drift to absolutely anything except what I'm trying to do. It seems to help to turn on an action movie and half-concentrate on that while I'm practising. Anybody else got any tips for giving the subconscious chance to get on with its work?
