Octave Pip Placement / Alteration Help

1882 Views 15 Replies 8 Participants Last post by  clarnibass
I have an issue with G# just above the Staff on Tenor. When I jump to it from anything in the Palm keys it cracks the harmonic.

I am certain that it has to do with the fact that it is the 1st note to be played using the Body's octave Pip - and thus being the one furthest from a perfect acoustic placement of that peticular pip.

Now, I can solve the issue by voicing it differently, however I was wondering if anybody had a mechanical solution to this issue.

The obvious one is to move the pip -and... um..... I dont see that happening anytime soon.

Who has other ideas or proven solutions?

Take a thin flat spring that is tapered (almost all of them are). The narrow end of the flat spring should be narrower than the inner diameter of the body octave key tube. The wide end of the flat spring should be at least as wide as the tube's inner diameter. The spring should be straight, not curved. Cut a length of the flat spring about 1/4" long, wide enough to go entirely into the octave tube and wedge itself just below the top of the hole.

Re-install the octave mechanism. If it doesn't improve the problem, get rid of it!

Alternately, use a cork pad on the lower octave key. Insert a short (1/4", maybe slightly longer) point from a needle spring throught the pad so that the pad, when installed, has a short needle protruding into the octave tube, even when the pad is open all the way. If this doesn't work, get rid of it!

The easiest solution is to use a softer reed, a looser embouchre, and more air.
