okay the comeback is going pretty good.. but I am at a cross roads.. I have this leak thing going on but my tone is pretty good ... I do believe my tone is a little on the spread side .. (but is has alwaysbeen that way) I recieved some pretty good ideas on how to eliminate the leak.. if I pull in my lips and put a little more of them in the mouthpiece the tone pinches but at the same time I can see that I can move around with much less movement ... lip trills become easier ... range is easier ... only problem is how it sounds ... but I don't think the sounds spreads with this setup. The embrochure I have always used was less lips in the mouthpiece but it is harder to perform lip trills and I feel like I have to work to move around... but the tone has always drawn compliements ... but it is not a standard orchestral sound .. When I watch players classical concert professonals they "appear" to have very little movement and their chops seem to be set in the mouthpiece.. I am looking for opinions here .. except for "ask my instructor" ... I will be fine and won't destroy my chops.. so try to stick with the tighter setup and work on openning the enbrochure as my chops build up stregth. or Don't screw with it .. work on building strength and pulling in the leaks.
