{{About|chromas in general|that in the diatonic scale|Chromatic semitone}} 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 in the [[diatonic]] scale is the [[chromatic semitone]], or 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 [[diamond-mos notation]], it should be noted that they are reserved exclusively for the diatonic scale, whereas am (&) and at (@) 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.
