Chroma: Difference between revisions

~~For~~ the ~~Fokker block concept~~ of chroma~~, see~~ [[~~Fokker block~~]].

The '''chroma''' (precisely the '''moschroma''') of a [[mos scale]] is the interval that is the difference between the large step and the small step in the scale. In particular, the chroma or '''chromatic semitone''' in the [[diatonic]] scale is the augmented unison, for example, the interval of C-C#.

~~The '''~~chroma~~'''~~ (~~precisely the '''moschroma'''~~) ~~of a [[mos scale]] is the interval that is the difference between the large step and the small step in the scale. The term was suggested as a way to generalize the concept of a sharp~~ or flat (~~# or~~ b). In ~~particular, the chroma or '''chromatic semitone''' in the~~ [[~~diatonic~~]] scale ~~is the augmented unison~~, for ~~example, the interval of C-C#~~.

In staff notation, alteration by the chroma can be represented by the sharp (#) or flat (b), as is shown above. In [[TAMNAMS]], it should be noted that they are reserved exclusively for the diatonic scale, whereas mossharp (&) and mosflat (@) are used for other mos scales.

Moving one note in a mos scale by a chroma leads to a [[modmos scale]] if the result is not just a transposition of the original mos scale.

The [[Fokker block]], being a generalization of the mos scale to higher ranks, also has the concept of chroma. See [[Fokker block]].
