HI! I joined this forum several months ago thinking that I would like to work on my own mouthpieces. After reading, here, how many factors are involved, I...
It gets trickier. The low register tunes by having the mouthpiece such that the volume of the chamber + bore past the neck cork is equal to the missing conical...
It's VERY tricky! It's about volume: the cubic capacity of the tone chamber should equal the cubic capacity of the missing portion of the truncated cone of the...
I was wondering if the size of the chamber exceeding the size of the neck is a problem? Or, should the size of the chamber (of the mouthpiece) lead conically...
Doesn't a curve in the bore have the same effect as enlarging the bore at that curved point? And doesn't that effect increase as the radius of the curve...
"so paul are you saying that the chamber is a cone within itself ??" Not at all! To tune the low register, the volume inside the mouthpiece, not just the...
Yes and yes. The effect is rather small, for instance a tube curving back on itself 180 degrees in a relatively tight curve (like a sax bow) increases the...
You are making a huge mistake. The truncation ratio is the length of the missing section at the top of the neck as a fraction of the total length of the tube,...
Thanks for the response. Paul says "It gets trickier." I hope that from the tone of my first paragraph that I acknowledge that. Tony says: "You are making a...
... I have read here some frustrations with trying to correlate calculated missing-volume with reality. I am suggesting that the neck is a poor indicator of...
In case anyone is interested, the fact is that the volume of the mouthpiece doesn't really matter until the length of the truncation is equal to or larger than...
What I meant is that you cannot leave the neck out of the equation just because its angle of conicity may be slightly different from the rest of the body or...
As you have already surmised, mpc volume changes quite significanly depending on its position on the cork. So as soon as you add temperature variation into the...
I have this mpc and the tip is almost gone, it's been worked on to the point of there being about 3/16" of material left at the center of the tip and even less...
It is probably shot. I'd pick up a used one off eBay for $100. If you do not want to give up, you can try some plumber's epoxy putty. I use Oatey brand I get...
As a practical matter, once the mouthpiece is playing as the designer wants, he simply adjusts the chamber volume, as I outlined previously, to get acceptable...
Yes, it is amazing the damn thing (saxophone, clarinet, whatever) plays at all. But with modern improvements we are getting close. Paul kymarto123@......
... <kwbradbury@...> ... putty. I ... metal MPs. ... Thanks Keith. Kinda figured as much. I might still give it a shot using the epoxy you've mentioned. ...
<<<< Most saxes are not true cones. They are somewhat parabolic. So the missing volume based on the neck taper would be smaller than based on the body taper. ...
... I got my info from Ferron's book and I have seen it elsewhere. Scavone seems to have done some nice work with his thesis. I'm surpised at his measurement...
I would recommend posting the files in the "Files" area at the Yahoo site. You can make a new directory if you wish. Then make a message post describing what...
The parabolic bore business is a myth. I've looked for it for years in the thousands of horns that have passed through my hands, and have yet to find a ...
I think we can only do so much as far as calculating, and it finally gets down to just simply "cut and try". Also, there are two papers, "Interactions Between...
Are there some people in this wonderful group who can tell me if alto- and bass clarinet need to have their own facing curve, more like usual clarinet facing...
I think I have in my files just about every dissertation written on saxophone design and acoustics. Paul correctly observes that there always comes a point...
Totally agree. The math gives you a good ballpark starting point, and then the real work begins ;-) Toby STEVE GOODSON <saxgourmet@...> wrote: I think I...
