I have noticed recently in my practices that I am losing my tone a bit when my articulations become more rapid. How can I remedy this? Got any tips or exercises. I have also noticed my point of attack is quite often incorrect. Van corrected my point of attack in lessons last year(I was tounging through my teeth). But, I guess I didn't really get the feel for the exact point where the tounge shoudl strike the ridge behind the teeth. Can anyone help me correct this with a exercise or something of the like. If long tones could have fixed it I am going to be very upset.
