Lol! Manny, somehow that last post sounded as though it was removed from a Monty Python skit!

I never knew you were so inclined.
More on task, how does one overcome the urge to close the oral cavity when playing and double tonguing from the middle range to the upper register? I guess I mean, how do you NOT raise your tongue (so as to keep the tonguing level consistent) but also raise the back of the tongue to help increase air speed? I am completely befuddled....
