No offense taken, I understand.
On the one hand, an expert player with a good ear can bend any note on almost any sax until it's in tune. On the other hand, that's not really the point of my experiment (as such). The results on my website are from tuning the midrange, then holding a steady embouchure, as recommended by sax instructors, and seeing what comes out.
Having said that... I'm working on my embouchure and I realize some (maybe most) of the intonation problems lie in my inexperience. Also, I have not had any of the instruments checked or adjusted at a shop, which I've neglected until I decide how seriously I want to pursue things. Finally, I understand the mouthpiece can make a big difference here and that my large chamber pieces may exaggerate intonation problems.
The alto results were especially disturbing and considering I tried a few variations of sax/mpc, either all my stuff is junk, or I simply can't play alto in tune. On the soprano and sopranino, I think I'm squeezing the high notes too much and making them sharp. However, if I play to the tuner and try to get the high notes in tune, on some I drop the jaw so far that I fall an octave before the note gets in tune.
I haven't had anyone else try my saxes. I have little contact with sax players of any type--just some quick conversations at concert band, where I play clarinet.
