Barbershop singers must then be superhuman, as most can and do sing way way way more accurately than this. >In the more usual timbres at least, the 7:6 interval beats too much to >be consonant, affected as it is by the unison.

All of the septimal intervals are used in Barbershop singing, and I've got some Barbershop that sounds like glass. Exposure to it has been known to cause paradigm shifts. >Your phrase "vanishing of the syntonic comma" is unfortunate. This comma >does vanish in the 22-tone equal, but at a value (218 cents) that leads >to excruciatingly dissonant 'major thirds' (436 cents) This third is only 1 cent off the 9/7, which is only dissonant if you use it like, or expect to hear a 5/4. Speaking of which, the 7th 22TET degree offers a 5/4 far better than 12 or 19 tone. Only 4 cents off. >minor thirds (273 cents) The 7/6 is the 7th superparticular, one of the most consonant intervals known to man. The 22TET, 6 cent deviation is very significant, however. >major sixths (927 cents) and minor sixths (764 cents) Inversions of the above.=20 >as soon as one modulates more than a few keys.
