The title says it all.
To better understand what goes on inside the saxophone when it is being played. The applications of this understanding are endless---anywhere from setting key heights to choosing the best equipment for your needs and preferences.You might need to expand on that. To what end?
Perhaps you could help us to decipher some of the math used by Benade and others in the published studies. My personal interests at this time include calculating the length and volume of the missing cone, measuring the "effective volume" of a mouthpiece and putting the two together to try to match the science to personal experience. I am also very interested in the effect of pad porousity on the tone and response of the saxophone all else being equal, and finding the causes and possible solutions to low note warbles. As a professional repair tech I am looking for ways to improve the intonation and harmonicity of saxophones by utilizing what is known about tube dimensions and note antinodes.That should be clear considering there's a subforum here with that exact purpose. If you're inquiring about the frequency of posts or new research, it comes down to the fact that there's no real money for research into musical instruments in the US. That much has been made clear as I've been pursuing a graduate degree in Acoustics. There are entire fields of research that don't get adequate funding. Room acoustics also suffers in this regard. Most of the best and most cited work was done decades ago and nowadays grants aren't given to dig deeper. It doesn't help that so much of the feedback from players uses pretty non-scientific language. Quantifying what the various descriptors of tone quality actually look like would be an undertaking in itself, not to mention finding methods to measure impedance for 'free-blowing' statements. It's all pretty nebulous and who is going to do the leg work without some guarantee of funding? It's hard to be a self-starting scientist when you usually need a pretty well-controlled environment.
Dirk, thank you for this wonderful resource!Yes.
Regarding the missing cone and the effective volume, there is interesting stuff to read in this French blog: http://la.trompette.free.fr/Ninob/Ninob.php.

Dirk, thank you for this great resource!

I don't know how well these articles will be translated by automatic translation software...
These threads have stuff about that in them:I'm interested, but know nothing about the topic. For instance, I'd like to know why it's often said that a horn's vibrations don't affect its sound in any way.
