George Secor, a composer from Chicago,〔Barbieri, Patrizio (2008). ''Enharmonic: Instruments and Music 1470-1900''; revised and translated studies, p.96. Il Levante Libreria Editrice. ISBN 9788895203140.〕 is the discoverer of miracle temperament and eponym of the secor. Secor and Hermann Pedtke's Motorola Scalatron (1974) is a Bosanquet generalized keyboard featuring a multicolored arrangement of 240 tunable oval keys, about which Secor said: "There is not much point in using this alternative keyboard for systems below 31 tones in the octave."〔Vail, Mark (2000). ''9780879306038'', p.101. Backbeat Books. ISBN 9780879306038.〕 However, "even if it were completely impractical musically, it would make a wonderful prop for a futuristic movie."〔 Though its synthesizer capacities may not reach performance level, according to Easley Blackwood, "It has rock-steady tuning capabilities; you can always count on it to be right."〔 ==Secor== In music, a secor is the interval of 116.7 cents () named after George Secor. Secor devised it to allow a close approximation, generated from a single interval, to Harry Partch's 43 tone just intonation scale. All 11-limit consonances are approximated to within 3.32 cents.〔"(Secor )", ''TonalSoft.com''. Accessed: July 2013〕 It is approximated in 31 , 41 , and 72 equal temperament .〔 For tuning purposes, a secor of seven steps of 72 equal temperament is often used. Two secors (233.4 ) approximate an 8:7 interval (231.17), a septimal whole tone. Three of these 8:7 intervals (693.51), or six secors (700.2 ), approximate a fifth (701.96). A neutral third of 11:9 (347.41) is approximated by three secors (350.1 ). 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「George Secor」の詳細全文を読む スポンサード リンク
