Frankly, I don't know what I was refering to. I thought I had remembered reading a reference to flat fifths somewhere; one hour of going through my notes yielded nothing, however. My apologies to yourself, Mr. Reinhard and members of this List for this flub. >> But you are correct in >> stating that Marpurg is wrong; What Marpurg probably meant to say >>was that if all the major thids where to be made wide, a major third, >> wide by a syntonic comma, was not possible. > > >But this is _still_ incorrect.

Sorry, my original quote should have read: "What Marpurg probably meant to say was that if all the major thirds where to be made [equally as] wide, a major third, wide by a syntonic comma, was not possible." Marpurg, however, was still wrong. The passage in question here is, admittedly, sloppy work on the part of Marpurg. As anyone familiar with his work in temperament knows, this is not characteristic of Marpurg's work, where he is one of the most precise writers in 18th-century Germany. >(It is curious to me that, while you insist the evidence is unambiguous, >you resort to interpretations and speculations like this one and the one >below.) I have spent many years reading the primary sources. In writing my dissertation, I've read all of Marpurg, all of Kirnberger and everyone else that dealt with tuning and temperament in Germany. Undoubtedly, I've missed some sources. But not a lot, I trust. Unlike today, when scientific writing tends to adhere to the "stylus dragneticus," 18th-century German scientific writing was very personal (there are exceptions) and one quickly becomes almost "personally" familiar with the writer. One knows how they thought and gets a strong feeling as to what they would react like given a certain set of circumstances. Spending so much time with them, I almost feel as if I knew these men, who died over 200 years ago. If I make a conjecture, it is based on this intimacy and a body of evidence. It is not incorrect jurisprudence to extrapolate postulates based on a given body of evidence and knowledge of the subject's past behavior. >So you'd rather trust Marpurg's slanted interpretation of Kirnberger's >statements, even though he makes a whopping big theoretical error in it? >Hmmph. Yes. One bumbling error does not the whole of Marpurg make. >The following two quotes are from _A History of Key Characteristics in >the Eighteenth and Early Nineteenth Centuries_, by Rita Steblin (UMI >Research Press, 1983), already cited once in this thread. > >p.91: >: It is known that Marpurg's attack caused Kirnberger much bitter >: anguish: he poured out his vexation in a series of letters to Forkel >: from 1779-80. . . . although Kirnberger did not publish a >: counterattack himself, he did include a defense written by the >: important mathematician and military officer at the Berlin court, >: Georg Friedrich Tempelhof (1737-1807). Although I admire Ms. Steblin's writings, I believe that she is wrong here. Although Tempelhof may have begun the review in question, Kirnberger himself (trying to pull a 'Marpurg') must have finished it. This is evident in the break of literary style (Tempelhof's and Kirnberger's litterary styles are completely dissimilar) and I would be very surprised indeed that if, upon meeting Kirnberger in the afterlife, he would tell me that Tempelhof wrote the whole thing... ;) >p.92: >: Marpurg, the avowed disciple of Rameau, had drawn clear battle lines >: between his theories in support of equal temperament and those of >: Kirnberger.

Bzzzz. Wrong again. The quote to which Ms.Steblin refers (contained in the infamous 23er Abschnitt of Marpurg's _Versuch_ ) is not about whether Kirnberger was being faithful to Bach or not. It was about Kirnberger's invocation of authority over empirical evidence. Read the section yourself, then we can talk (_Versuch_ [1776], pp.182-219). >: Marpurg then >: appealed to Bach's sons to substantiate him in his claim, but this ruse Marpurg actually *quoted* C.P.E.

Wow. Ms. Steblin streches quite a bit in drawing this conclusion. (Her translation isn't very good either.) My feeling is that the passage in question refers to Marpurg's _Versuch_ on the whole (remember that the second half of the _Versuch_ (90-some pages) has nothing to do with temperament but is a giant polemic on Kirnbergers harmonic theories as opposed to Rameau's (which Marpurg really didn't fully understand himself).
