G10H2210/471 - CPC Classification

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 Natural or just intonation scales, i.e. based on harmonics consonance such that most adjacent pitches are related by harmonically pure ratios of small integers

• G10H2210/476 » Zarlino scales, e.g. octave subdivision based on the pitch ratios 9/8 + 10/9 + 16/15 + 9/8 + 10/9 + 9/8 + 16/15 0
• G10H2210/481 » Pythagorean scale, i.e. in which the frequency relationships of all intervals should be based on the perfect fifth, with ratio 3:2 3
• G10H2210/486 » Werckmeister scales, i.e. family of scales with 12 mostly rational intervals, e.g. for organs 0
• G10H2210/491 » Meantone scales, i.e. in which all non-octave intervals are generated from a stack of tempered perfect fifths; and wherein, by choosing an appropriate size for major and minor thirds, the syntonic comma is tempered to unison, e.g. quarter comma meantone, syntonic comma, d'Alembert modified meantone 1
• G10H2210/496 » Redfield scales, i.e. 12 intervals per octave, based on note ratios equal to (2**p)*(3**q)*(5**r) with p,q, r positive or negative integers 0
• G10H2210/501 » Altered natural scale, i.e. 12 unequal intervals not foreseen in the above 2
• G10H2210/506 » Danielou 53 interval scale, with note ratios equal to (2**p)(3**q)(5**r), with p,q,r positive or negative integers 0
