A chromatic scale may received a mirror whose any note can act as pivot but the mirror has to be in the tonality of the whole tone scale. Only the first half of a chromatic scale appear in one direction as pivot so the original chromatic scale must have to separated part
- from tonic to triton
- from triton to tonic
In the descending chromatic scale the slope of the pivots line is inverted.
All tonalities of the mirror are available thanks to another chromatic scale starting on C# that provides the second whole tone scale.
Caution:E scale as mirror is different from the E chromatic scale.
Here the E scale is the mirror of a C chromatic scale with D as pivot
Now E is the mirror of a E chromatic scale with two pivots E and Bb
Therefore to start a chromatic scale with another degree one must define the whole tone scale and the triton
