Chromatic scale and new notes between E/F and B/C: The fractions and , and , and , and , and many other pairs are interchangeable, as (syntonic comma) is tempered out. These are 19-EDO just intonation approximations. The ancient Chinese chromatic scale is called "Shí-èr-lǜ". However, "it should not be imagined that this gamut ever functioned as a scale, and it is erroneous to refer to the 'Chinese chromatic scale', as some Western writers have done. The series of twelve notes known as the twelve "lü" were simply a series of fundamental notes from which scales could be constructed." The Indian solfège,
Double harmonic scale harmonic minor scales respectively, each of which, unlike the double harmonic minor scale, has a full diminished chord backbone. This scale (and its modes like the Hungarian minor scale) is the only seven-note scale (in 12-tone equal temperament) that is "perfectly balanced"; this means that when its pitches are represented as points on a circle (whose full circumference represents an octave), their average position (or "centre of mass") is the centre of the circle. Like most heptatonic (seven-pitch) scales, the double harmonic scale has a mode for each of its individual scale degrees. The most commonly known of these modes
