I can play Altissimo like hell on my Alto, but when it comes to the Tenor, I can't find many fingerings that will work with my Mark VI. I use the fingering 1o3,1o3 for G on my alto, and then add the middle RH Palm key to make it G#. A is o23,ooo, then to A# is o23,12o with the middle RH palm key. Anyways, I try to use these fingerings including more on my Tenor, but I can't seem to find any fingering that will pull off my G. Anything above it is hard to get too. I'm not sure if it could be my airflow or whatever, but I'm doing the same things I do on my Alto. If anyone has found this difficult on their Mark VI or any model by chance, please advise me on what I can do to be able to pull it off and make it all work out.
