<HTML>I even dared practice some Two Part Inventions in MT.     While I like setting the temperaments of HT's it is a major chore to tune the rest of the piano.  Perhaps I should have a harpsichord.  Bach was said to tune his harpsichord in 15 minutes. What I would really like is a digital keyboard that has a choice of temperaments and can be programmed for even more.  But don't count on the accuracy. Go to  you local piano store and check the temperaments of the digitals.  You might be surprised.   ---ric </BLOCKQUOTE> RicM already knows about all this, but I thought I'd post my impressions to the List on this matter.  A year ago I was storing (well, borrowing, I suppose) a small spinet harpsichord while the department I worked in was undergoing renovation of the HVAC system.  During that summer I spent considerable time tuning and playing that little instrument.  I kept the Pietro Aaron MT on it for most of that time, based on the bearing plan from Jorgensen's little book.  To echo Ric's statement, I, too, spent time playing the 2-Part Inventions of Bach, surmising that he might well have written them for an instrument likely tuned in MT (the WTC was specifically designed for some sort of WT, which would have been quite different, I think).  What struck me was how usable the MT was for this music, and in looking at it from a Music Theory teacher's perspective, I saw that the Inventions which were in the more remote keys were also carefully written--not to eliminate the wolf, which would obviously not be possible, but to minimize its effect.  Had I the same kind of historian's bent that Ric has, and had I had more time to experiment and research, I would like to have done a more rigorous theoretical study of the 2-Part Inventions, with the premise that they were written with MT in mind, and how that affected the manner in which they were written.  From a rather cursory inspection, it seemed that good ole JSB had very neatly circumvented many of the problems associated with MT, but I'd really have to spend a lot more time than I had in order to nail it down.  So it remains an impression--but it was quite a strong one on me!
