<HTML>Thanks for all the comments and suggestions. Ed answer= ed the question I was looking for, when he said, "I have noticed that the ch= aracteristic of any given temperament seems the same on various pianos, but = the level of brilliance can change how strongly tempered the remote keys fee= l." I concluded, perhaps wrongly, that a difference in tone can make a tempe= rament sound a little different on different instruments. After all, we use = different temperaments on different pianos. So why wouldn't an HT be differe= nt, even if it is superimposed on the temperament of the piano? For what it's worth, this is how we remedied the situation. I tuned the pian= o to the Jousse, as per Owen's instructions, with a slight modification as p= er another tuner. Then we went through each interval, as per Jousse' 1832 be= aring plan number one, and adjusted a few intervals as per the piano profess= ors instructions, "tweaking" them just enough to make them sound correct for= the Boston. I then recorded the new temperament in my SATIII, and redid the= whole piano. Wim </HTML>
