The Harmonic Scale is a "super-Just" musical scale allowing extended just intonation, beyond 5-limit to the 19th harmonic (), and free modulation through the use of synthesizers. Transpositions and tuning tables are controlled by the left hand on the appropriate note on a one-octave keyboard.〔Milano, Dominic (November 1986). ("A Many-Colored Jungle of Exotic Tunings" ), ''Keyboard''.〕 For example, if the harmonic scale is tuned to a fundamental of C then harmonics 16-32 are as follows: Some harmonics are not included:〔 23, 25, 29, & 31. The 21st is a natural seventh above G, but not a great interval above C and the 27th is a just fifth above D. It was invented by Wendy Carlos and used on three pieces on her album ''Beauty in the Beast'' (1986); ''Just Imaginings'', ''That's Just It'', and ''Yusae-Aisae''. Versions of the scale have also been used by Ezra Sims and Frans Richter Herf. ==Number of notes== Though described by Carlos as containing, "144 () distinct pitches to the octave," the twelve scales include 78 (=12(12+1)⁄2) notes per octave. Technically there should then be duplicates and thus 57 (=78-21) pitches (21=6(6+1)⁄2). For example, a perfect fifth above G (D) is the major tone above C. 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「Harmonic Scale」の詳細全文を読む スポンサード リンク
