Symmetric scales

What are symmetrical scales

Symmetric scales consists of repeated symmetric intervals. The octave is divided in equal parts. The four most important symmetric scales are :

The chromatic scale :

C chromatic scale

The whole tone scale :

The whole tone scale is an hexatonic scale, it contains six notes. The octave is divided into six equal parts formed by a serie of whole tones. There are only two whole tone scales.

C whole tone scale

Db whole tone scale

The diminished scales :

There are two modes depending on whether we start with a tone or a half tone and only three scales for each mode.

The Whole half diminished scale (also called diminished scale) :

C diminished scale	C	D	Eb	F	Gb	Ab	A	B
Formula	1	9	b3	11	b5	b13 or #5	13	7

The half whole diminished scale (also dominant diminished scale) :

C Dominant diminished scale	C	Db	D#	E	F#	G	A	Bb
Formula	1	b9	#9	3	#11	5	13	b7

The augmented scale :

It is formed by musical cells that contains a minor third & a semi-tone.

C augmented scale	C	D#	E	G	Ab	B
