Greetings, Most of the temperaments documented by Barbour,(and later by Jorgensen) have at least one third that is tempered by the full syntonic comma (21.5 cents). This is quite a bit different than the 13.7 cents found in an ET third. Bill again: >>I rarely choose to tune such an extreme and early temperament as the 1/4 Comma Meantone. <snip>It really messes up a piano's tuning, however, about like a 25 cent pitch change might do.<< I must partially disagree. Our next temperament CD has a Scarlatti piece (K96) recorded in 1/4 C on a Steinway D. We recorded it last, as I feared the piano would be completely destablized. However, when I retuned the piano to ET, I found that the A's were exactly where they should be without me touching them. The overall tension on the piano appears to have been the same for ET as MT! Some indivdual enharmonic notes required a second tuning the next day, but changing to 1/4 C is not nearly so drastic a stress on the piano as a 25 cent pitch change. Regards, Ed Foote RPT
