User:HeroeDelfin/Ekisde Scale

In music, the scale name Ekisde [e 'kiz ðe] is attributed to the technically known as The double major harmonic scale (in D), consisting of 7 notes (D, Eb, F#, G, A, Bb ,C#).

This name belongs to the letters of the Spanish alphabet "X" and "D", (name devised by Daniil Tikhomirov better known as daniiiiekisde), since "XD" expresses "laughing out loud". Turning it 90º to the right resembles the representation of a face with a wide open mouth and eyes tightly pressed as a symptom of a loud laugh. At first glance, it does not have a logical sense as a name, but the exoticism of the oriental scales is given a sense of humor, transforming them into a sense of contemporary culture.

Thus, there is a reflection on the passion of art and life, Ars longa, vita brevis.

Details
The major harmonic double scale (in D), has the interval structure:

h (W+h) h W h (W+h) h (W: Whole tone, h: half tone)

1 b2 3 4 5 b6 7.

The sequence of steps comprising the double harmonic scale is:

semitone, augmented second, semitone, major second, semitone, second augmented, semitone

Or, in relation to the tonic note:

second minor, third major, fourth and fifth perfect, sixth minor, seventh major

However, this scale is commonly represented with the first and last half step, each represented with quarter tones.

The non-quarter tone form is identical to the North Indian Thaat named Bhairav and the South Indian (Carnatic) Melakarta named Mayamalavagowla. The double harmonic scale is arrived at by either:


 * raising the seventh of the Phrygian dominant scale, (a mode of the harmonic minor scale), by a semitone.
 * raising the seventh and third of the Phrygian mode, (a mode of the major scale), by a semitone.
 * lowering both the sixth and second of a major scale by a semitone.
 * lowering the second note of a harmonic major scale by a semitone.
 * lowering the second note and raising the third note of the harmonic minor scale by one semitone.
 * combining the lower half of Phrygian dominant scale with the upper half of harmonic minor

Symmetry and harmony
The double harmonic scale features radial symmetry, or symmetry around its root, or center note. Breaking up the three note chromaticism and removing this symmetry by sharpening the 2nd or flattening the 7th note respectively by one semitone yields the harmonic major and Phrygian Dominant mode of the 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.
