Symmetric scales consists of repeated symmetric intervals. The octave is divided in equal parts. The four most important symmetric scales are :
The chromatic scale :
The octave is divided in 12 equal parts, it is formed by a succession of half-tones, there is only one chromatic scale, it contains 12 notes.
|C chromatic scale||C||C#||D||D#||E||F||F#||G||G#||A||A#||B|
The whole tone scale :
Is an hexatonic scale, it contains six notes. The octave is divided in six equal parts formed by a serie of whole tones. There are only two whole tone scales.
|C whole tone scale||C||D||E||F#||G#||A#|
|Db whole tone scale||Db||Eb||F||G||A||B|
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|
The augmented scale :
It is formed by musical cell that contains a minor third & a semi-tone.
|C augmented scale||C||D#||E||G||Ab||B|
|Formula||1||b3||3||5||#5 or b13||7|
