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#. | 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.

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. | 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. | ||
