Equally tempered scale, i.e. note tuning scale in which every pair of adjacent notes has an identical frequency ratio equal to 2 to the power 1/n if the scale has n notes per octave

Full Title

Aspects or methods of musical processing having intrinsic musical character, i.e. involving musical theory or musical parameters or relying on musical knowledge, as applied in electrophonic musical tools or instruments > Special musical scales, i.e. other than the 12-interval equally tempered scale; Special input devices therefor > Equally tempered scale, i.e. note tuning scale in which every pair of adjacent notes has an identical frequency ratio equal to 2 to the power 1/n if the scale has n notes per octave

• G10H 2210/421 10 equal intervals per octave
• G10H 2210/425 19 equal intervals per octave, offering better major thirds, far better minor thirds and overall far greater consonance than normal 12-semitone equal temperament, at the cost of a flatter fifth
• G10H 2210/431 Quarter tone scale, i.e. 24 equal intervals per octave, e.g. for Arabic music
• G10H 2210/435 Huygens scale, i.e. 31 equal intervals per octave, provides near-just major thirds, and provides decent matches for harmonics up to at least 13, despite a slightly less accurate fifth than the standard 12 interval equally tempered scale
• G10H 2210/441 Janko scale, i.e. 41 equal intervals per octave, e.g. as used in the "tonal plexus" keyboard with 211 keys per octave arranged in 12 staggered columns, i.e. in 41 regions of 5 keys each plus 6 duplicate enharmonic keys
• G10H 2210/445 45 equal intervals per octave
• G10H 2210/451 Holder scale or Holdrian comma, i.e. 53 equal intervals per octave, with 31 intervals equal to an almost just perfect fifth; Keyboards therefor, e.g. "generalized keyboard" of Robert Holford Macdowall Bosanquet
• G10H 2210/455 70 equal intervals per octave
• G10H 2210/461 Jankovski scale or twelfth tone scale, i.e. octave divided in 72 equal intervals, e.g. moria in Byzantine music theory
• G10H 2210/465 84 equal intervals per octave
