septimal chromatic semitone : ウィキペディア英語版 | septimal chromatic semitone
In music, a septimal chromatic semitone or minor semitone〔Haluska, Jan (2003). ''The Mathematical Theory of Tone Systems'', p.xxiv. ISBN 0-8247-4714-3.〕 is the interval 21:20 (). It is about 84.47 cents. The septimal chromatic semitone may be derived from the harmonic series as the interval between the twentieth and twenty-first harmonics. The septimal chromatic semitone equals a just chromatic semitone plus a septimal semicomma (the interval 126:125). When added to the 15:14 semitone, the 21:20 semitone and 28:27 semitone produce the 9:8 tone (major tone) and 10:9 tone (minor tone), respectively. ==References==
