[TPIN] Air Leakage While Tonguing

[Brett Johnson]

Hi all,
I've had this little problem for a while now, but I was recently practicing 
and it really stood out. I've been *trying* to work on my multiple tonguing 
to prepare for a concert piece in school. I don't have the "ideal"-shaped 
tongue. Mine is fat and round. Whenever I approach about an E or F near the 
top of the staff, I have air leaking from just outside the mouthpiece, and 
when I try to tongue fast I get nowhere. My speed drops considerably, 
sometimes just cutting off the note.  As you might expect, this could hold 
me back while playing this song, as it calls for high C's, and I have to 
take it down an octave. I don't like taking things down :-). I do use a 
rather big mouthpiece (Schilke 20) if that has any relevence. Seems like I 
need to correct something big here. All help would be really appreciated.
Thanks,
Brett
