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, such as 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.

== History == | |||
The first mention of the term "chroma" occurs in Marchettus of Padua<ref>Marchettus of Padua (1318) ''Lucidarium''.</ref> where he describes it as an interval smaller than the diatonic semitone. The exact nature of the interval he was describing is debated.<ref>Joe Monzo (2008) ''Speculations on Marchetto of Padua's "Fifth-Tones"''. http://www.tonalsoft.com/monzo/marchetto/marchetto.aspx</ref> | |||
