Werckmeister: Musicae mathematicae hodegus curiosus oder Richtiger Musicalischer Weg-Weiser (Quedlinburg 1686, Frankfurt & Leipzig 1687) ISBN 3-487-04080-8〕〔A. Werckmeister: Musicalische Temperatur (Quedlinburg 1691), reprint edited by Rudolf Rasch ISBN 90-70907-02-X〕 The tuning systems are confusingly numbered in two different ways: the first refers to the order in which they were presented as "good temperaments" in Werckmeister's 1691 treatise, the second to their labelling on his monochord. The monochord labels start from III since just intonation is labelled I and quarter-comma meantone is labelled II. The tunings I (III), II (IV) and III (V) were presented graphically by a cycle of fifths and a list of major thirds, giving the temperament of each in fractions of a comma. Werckmeister used the organbuilder's notation of ^ for a downwards tempered or narrowed interval and v for an upward tempered or widened one. (This appears counterintuitive - it is based on the use of a conical tuning tool which would reshape the ends of the pipes.) A pure fifth is simply a dash. Werckmeister was not explicit about whether the syntonic comma or Pythagorean comma was meant: the difference between them, the so-called schisma, is almost inaudible and he stated that it could be divided up among the fifths. The last "Septenarius" tuning was not conceived in terms of fractions of a comma, despite some modern authors' attempts to approximate it by some such method. Instead, Werckmeister gave the string lengths on the monochord directly, and from that calculated how each fifth ought to be tempered. ==Werckmeister I (III): "correct temperament" based on 1/4 comma divisions == This tuning uses mostly pure (perfect) fifths, as in Pythagorean tuning, but each of the fifths C-G, G-D, D-A and B-F is made smaller, i.e. tempered by 1/4 comma. Werckmeister designated this tuning as particularly suited for playing chromatic music ("''ficte''"), which may have led to its popularity as a tuning for J.S. Bach's music in recent years. Modern authors have calculated exact mathematical values for the frequency relationships and intervals using the Pythagorean comma: ||0 |- |C ||$\backslash frac$ ||90 |- |D ||$\backslash frac\; \backslash sqrt$ ||192 |- |D ||$\backslash frac$ ||294 |- |E ||$\backslash frac\; \backslash sqrt()$ ||390 |- |F ||$\backslash frac$ ||498 |- |F ||$\backslash frac$ ||588 |- |G ||$\backslash frac\; \backslash sqrt()$ ||696 |- |G ||$\backslash frac$ ||792 |- |A ||$\backslash frac\; \backslash sqrt()$ ||888 |- |B ||$\backslash frac$ ||996 |- |B ||$\backslash frac\; \backslash sqrt()$ ||1092 |} 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Werckmeister temperament」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
