Why AMT (amity)?

Dear Gene,

The acronym stands for "acute minor thirds". But the generator is
c.340 cents. Isn't that an _obtuse_ minor third, not an acute one?

Confused,
Paul

The amity generator is a slightly sharp 243/200, and 243/200 is listed
by Manuel as "acute minor third", the only interval which he calls by
this name. I presume "acute" means "sharp".

Oh, right . . . presumably "acute" is the opposite of "grave" somehow
(I don't know if I'd rather have acute pancreatitis or grave
pancreatitis).

Another question -- why "semisixths" but "hemifourths"? Why
not "semifourths"? A hyphenated use of the latter word is found here:

I presume the lack of a response means "no reason"?

Actually it meant "I liked the sound better, and hadn't read xen3a.pdf".
