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. 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 [[TAMNAMS]], it should be noted that they are reserved exclusively for the diatonic scale, whereas mossharp (&) and mosflat (@) are used for other mos scales.
