I'm having a mishap with my High G to on my yamaha 62. it's normally the timing of your octave key. It's on the G, but my teacher says it happens on D too. at first I thought it was my neck, but then it turned out to be me. try putting down the octave key after you put down your other keys. See if the G works. If it doesn't then somethings wrong with your neck, and you should check it out. 10M's do have different necks then modern saxes., so you should check it out.

When I jump to G (or G#) the tone comes out multphonic, harsh, raucous, and offensive. If I carefully rearrange my embouchure first (tighten my lips, with a narrower throat, so the air seems to bounce off my upper palatte) then I get a decent tone. This works o.k. with long tone practice, but when I'm playing fast or trying to improvise, that offensive noise sometimes pops out. The body octive vent responds pretty closely with the octive key, but I'm going to try to clean out the tone hole--maybe it's partially clogged with lint or something. If that works, I'll be very happy (but I doubt it's the problem). The neck is single socket. My instructor also told me that a mouthpiece with a larger chamber would be best with this horn. When my current spate of bills get paid, I'll probably start thinking about a change. Thanks, SM. BTW, what size chamber, and/or MP would you recommend? Tenor--I don't think it's the neck, because I've tried variations on the sequencing of key depression. Thanks, though. My instructor thinks I should just train my emboucher to adjust, until I do it naturally in the course of playing. But it can get frustrating!
