+1 on this.

 

could be a leak somewhere, most likely it's a problem with your octave mechanism seeing as it only happens on G2/ G#2 .

I would first check your octave mech to ensure that when you play your G with the octave key pressed, the body octave key is open and the octave key on the crook is fully closed and the pad is sealing on the octave pip. ( it should be the reverse when you play an A e.g. body pip closed and crook key open)

check also that you have some clearance between the loop on the crook key and the arm that operates it .

seeing as we're in the beginners section of the forum, it could be that its your embouchure/mouthpiece or reed causing this .

 

I just picked it up from the shop. It did have several leaks and had other adjustments done, which I thought would take care. I checked for the leaks there are none. I do have another cheap tenor, its an easy fix with the embouchure on that one.

 

Try experimenting with the shape of your aural cavity and embouchure, when I get really tired after a long practice session I sometimes play 2G/G# flat or with the wrong shape which causes the notes to growl, after a 10 minute break all is well again. Start practicing the attached overtones, it will train and strenghten your vocal tract and chops.

 

Yes, this is all in how you're voicing the notes along with air support and possibly too much pressure on the reed (biting). I have the same horn you do (66R) and had this same problem for quite a while. I fixed it by making sure I was pushing air from my belly and working on loosening up the jaw and voicing techniques. I really think the Mauriat horns for some reason exacerbate this G2 G#2 problem... not sure.

 

I agree with you buddy lee about the Mauriat horns. Air support is not an issue, I just have to put more pressure on the reed to sound good. My cheap horn is such a minor adjustment that I don't even notice it.

 

When I tried a new Mauriat I had the same problem of the note breaking up...G & G#....would be interesting to have serious answers to this...one Series III that I tried had the same problem, but not the one I use all the time, or any other of the many horns I have played over the years. It's presumably something simple?

 

No clue, this would be something for an acoustical engineer to tackle HOWEVER with a lot of focused work on my part I've gotten to the point where I can play G2/G#2 without the splitting issues. Maybe the Mauriats are just less "forgiving" on these two notes?
