Hi Manny, so since your last post giving advice about this, I've been working quite hard on it. I've got up to the stage where my "ka" sounds like my "ta" and have been working on chromatic scales - coordination with the fingers is coming along. I do have some problems though: If I double tongue a chromatic scale from G below the staff to G on top of it, the low notes (~G-B) sound very "flabby", without a nice clean attack, and sometimes the upper notes get pinched on the "k" syllable. On the upper ones I sometimes feel tension in my throat, so I think that's the problem there. Any tips for getting those low F#s and Gs sounding as crisp as the ones in the middle register? Cheers, Jack.
