o its ur 2nd octave E and F?? then mabey ......not sure. my apologies I thought you meant 3rd octave E and F

just to clarify, Starting at the bottom of the sax, it's the 3rd octive up- E and F. On the Music staff it's above the G that sits above the staff. I know them as Front E or Front F. I already had the horn looked at, when I got it back the whole horn played easier, but still had the problem, maybe a little less persistant. I initially contributed it to getting use to the air flow of a new horn, but the probelm remains as I have become used to the horn.

Well you can play beyond that depending what size your mpc and reed is... Before I knew much about jazz our teacher bought us these crappy mouthpieces but they were big and I was using a way to big reed on them (Extremely hard to play) and If i bit down hard as i could i could go to the 5th octive D (pissed everyone off) it gets to a point where its just a squeek...harder you bite the sharper it gets...haha. but it was near impossible to get a 3 G or A etc. But if I use a reed the right size for me to hit those, the highest I can get up to is probably a 4th A...but it kills my lip...and I never go that high except in the gordon goodwin song "Count Bubba" the high school trumpets cant hit a double c at the end so I play a 4th G and sounds ok=). Our trumpets are worthless...
