12-tone tertial Rational Intonation scale, derived from harmonic series intervals up to a prime limit of 3, ranging from G♭ to B, centered on C. Also commonly known as PythagoreanPythagorean tuning is an approach to tuning based on stacking pure fifths (i.e. fifths with an exact frequency ratio of 2:3).Visit the link to learn more or Ancient Mesopotamian tuning, based on perfect fifthsPitches a fifth apart have a 2:3 frequency ratio (in just intonation) or a difference of 700 cents (in 12 tone equal temperament).Visit the link to learn more. The five chosen chromatic pitch spellings (D♭, E♭, G♭, A♭, B♭) are based on the usage of perfect fifths documented in the later 14th and 15th Centuries (de Zwolle et al).
