Manny, The other day I was working on the Arutunian double tounging sections, and I noticed I'm starting to get that smooth yet defined tounging in the lower register, just like the Dokshizer recording... But as I extend into the upper register, it starts to get a bit harsh... I know that it just comes down to practice, but I was wondering if you could help me with a physical Image of how my mechanics should stay the same or change as I move up the scales. I've been focusing on a Tu-Ku (or Too-Koo) rather than a Du-Guh approch, and it seems to help, but I'm looking for even more clarity. Thanks for any input you may have.
