Sorry if you misunderstood academic manners -- an "adversarial" stance is adopted only in order to sharpen arguments (granted, the temperature can rise somewhat if a lucidly stated argument is distorted). Furthermore, I've strongly hinted before that I'm playing devil's advocate -- I'm not against what you say, but I want to hear the best possible arguments for the case, so that even the most dogged and sceptical supporter of the 18th-century ET thesis will be convinced. > > Walker asks; > > if ET was well-nigh impossible in the 18th century, as you > >argue, how come it was in popular use for lutes and viols during the > >16th century? > The placement of frets, by linear measurement, is a piece of cake > compared to tuning by string tension.

Here's an example, I think, of the adversarial game drawing out a better argument. In reply, I suppose one might ask why a fretted string instrument could not then be used as a point of reference by the keyboard tuner. But otherwise I'm satisfied on this matter. > However, to say that I am trying to "label anything with > noticeable differences a well-temperament" does something of a > disservice to my intentions.

So what you would want to establish is that 18th-century keyboard tuners considered the achievement of ET, accurate beyond audible margins of error, considered such a hopeless task that it was not worth attempting. If so, I trust that we would eventually be able to find some recorded statements to this effect. > >[JW] forgive me if I'm disinclined to > >accept any far-reaching thesis purely on the grounds that the ears of > >some (no doubt able) musician have convinced him of its truth. > > This thesis is not, in all fairness, based purely on the the ears. > The opinions formed by listening have a substantial amount of > historical support, do they not?

I'm afraid that this, and much else that you've said, goes no further than to say that well-temperament was a possibility for this music. But I never argued with this. What I was asking you to do, rather, was to back up your categorical statement that equal temperament was _not_ used at all (as a keyboard tuning) in Germany/Austria c.1800. I suspect by now that you said all you can on this matter, and I thank you for this. My concern is simply that there is not so far any case which would withstand scrutiny as an academic paper; since your interests are practical rather than academic, you may not be worried by this. But it will prove a difficult task, since at present revisionists such as Rudolf Rasch, are (as Manuel Op de Coul reminded us) prepared even to say that Bach might indeed have intended the WTK for equal temperament, notwithstanding all that has been argued to the contrary. If respected academics are still prepared to place ET (as a keyboard tuning) back even as far as the 1720s, there is a great deal to be done before we can hope to establish the counter-thesis that ET didn't begin to emerge as a practical possibility (for keyboards) until at least a century later. Whatever the merits of Rasch's case, there is a very long way to go before the historical case for the prevalence of well-temperament into the 19th century has been established. There are two routes by which we can attack the consensual thesis that ET was well-nigh universal in Germany/Austria by 1800: one is to provide convincing documentary evidence to the contrary from contemporary sources (I've still seen nothing in this respect); the other is to shift the burden of proof onto those following the consensual thesis, by demonstrating that ET was so far beyond the capabilities of 18th-century tuners that its supposed establishment by 1800 is most improbable (you have said a couple of things which move in this direction). Does anyone know of more material, or can anyone suggest further arguments which would contribute to either of these possible lines of attack? > >Was Chopin (advocate of ET, as I've said before) less than > >a true musician? > No, but Chopin was not composing music in the time of Mozart and > Beethoven, I assume he cut his teeth on a lot less meantone than > Beethoven, or Mozart. Meantone? Yes, probably 1/6-comma from good string players, and on some keyboards (it was Silbermann's choice), but I thought we were talking about well temperament. Was this a typo? In any case, would you agree then that for music which modulates freely, but which remains locally diatonic in most passages (as in Beethoven), well-temperaments are best, but where local chromaticism becomes more prevalent (as in later Chopin), then equal temperament is more satisfactory? > (For a real treat, listen to his Opus 28 > preludes performed on a DeMorgan temperament. It is a very different > music indeed, and it could have happened!) Definitely a typo here (op. 39 Preludes "durch alle Tonarten"). The date of composition is thought to have been 1789 -- certainly a later Bonn work -- so the opus number, 39, is misleading in this respect. In this case, even if (contrary to your view) ET was prevalent by 1800, there is still a fairly high probability that in relatively provincial Bonn, well temperament would still have been much in evidence at this date. Tuning matters aside, I find it particularly interesting that the two preludes traverse the circuit of keys in different ways: the first reaches C# major by fifths, then manages to reverse all of this and more in a wonderful chromatic passage to arrive on a genuine Db major (genuine in the sense that it is not just a notational convenience), whereupon the fifths sequence resumes until the final (genuine) C major is reached. The second prelude, maintains the fifths sequence throughout, and passes through the cycle twice, so removing changes due to notational convenience, we pass from C major to A*# major. The first prelude even manages to maintain a high level of inventiveness, and deserves to be heard more often on the concert platform. -- Jonathan Walker Queen's University Belfast mailto:kollos@cavehill.dnet.co.uk http://www.music.qub.ac.uk/~walker/ Received: from ns.ezh.nl [137.174.112.59] by vbv40.ezh.nl with SMTP-OpenVMS via TCP/IP; Mon, 10 Mar 1997 18:30 +0100 Received: by ns.ezh.nl; (5.65v3.2/1.3/10May95) id AA00736; Mon, 10 Mar 1997 18:30:40 +0100 Received: from ella.mills.edu by ns (smtpxd); id XA00734 Received: from by ella.mills.edu via SMTP (940816.SGI.8.6.9/930416.SGI) id JAA29173; Mon, 10 Mar 1997 09:27:24 -0800 Date: Mon, 10 Mar 1997 09:27:24 -0800 Message-Id: <199703101726.AA06357@eceserv0.ece.wisc.edu> Errors-To: madole@mills.edu Reply-To: tuning@ella.mills.edu Originator: tuning@eartha.mills.edu Sender: tuning@ella.mills.edu
