Hello. I had my first lesson with Abram and we talked about tongue placement being key to vowel modification. For instance, eee and ooo tongue placement high, ahh low. But I'm a right in believing that the you use the jaw to achieve tongue placement. Doesn't seem possible to manipulate the base of the tongue independently. Hope that makes sense.

Thanks, Tim

Hi, Tim! It's possible (and desirable) to achieve independence between the jaw and tongue. See this short lesson for some explanation and advice!
