My problem is not creating the attack, the ‘T’.
But the 2 draw bends immediately.
Today I’ve tried different things with my mouth, and it seems I need to play the 2 draw only with a ‘Teeeeeeeeeeeeeeeeee’ (tiiiiiiiiiiiiiiiiiiiiiii) shape.
As soon as I try ‘Ta’ or anything (meaning, more space above my tongue), the tone bends.
No diaphragm at work here, so far.
