Well, that is certainly a commonly accepted statement. I'm not sure that it is accurate. Looking at the most reliable information, the measurements of Alexander Ellis, we have proof that WT principles survived into the 1880s in Broadwood's Best #4. (And we have Ludwig the Steinway tuner as well, and other anecdotal information, suggesting the traditions survived into the 20th century, including mean tone procedures). But we also have others of Ellis' measurements (including Broadwood's Best #5) which show a very close approximation of ET. So close that I doubt very much any of us could distinguish (unisons being equal) from a very precise ET - in actual performance, not slow listening to interval sequences. Jorgensen's major thesis is that ET was not practiced in fact before the 20th century (because of lack of precise enough instructions). This thesis is based on a definition of ET as "able to pass the PTG tuning test." Is this actually an appropriate threshold? I am not convinced that it is. I think there is a much wider range of "quasi- ET" that is, for practical purposes, indistinguishable from ET, unisons being equal. That is, that neither sharp-eared musicians nor sharp-eared tuners (with possible rare exceptions) would be able to hear a musical difference, let alone a general public. Much of Jorgensen's work on so-called "Victorian temperaments" is an attempt to intuit what "mistakes" would be likely to to occur following a particular temperament sequence, even though the sequence itself prescribes ET quite explicitly, and certainly does not "ask for key color." It is certainly true that the historical data are mixed. For many years, there was an acceptance of the false notion that ET was generally practiced from the time of Bach. In the zeal to correct this historical error, a contrary opinion has been promoted: that ET didn't exist, or at least that WT was prevalent, to the end of the 19th and beginning of the 20th century. I don't think either position is true. I think that several tuning traditions lived side by side, from the early 18th century through the early 20th, and that very reasonable approximation of ET was one of them from fairly early in that span. There was a strong movement in favor of ET from at least the early 19th century, with almost all tuning instructions purporting to lead to ET. So while one musician/ composer might well be exposed to non-ET tuning for the most part (because of the strength of tradition over theory), and another mostly to "quasi-ET," we have no way of knowing which was which, or whether they cared. Unless they tell us. Hummel tells us he didn't care. Schubert didn't tell us anything about tuning. We're left hanging, but at least we have fodder for endless conversation <G>.
