CHROMATICALLY ALTERED PASSING TONE
A chromatically altered passing tone fills the interval of a third between two chord tones and uses an accidental. It appears in either a weak or strong rhythmic position. Chromatically altered passing tones occur most often in the ascending melodic minor over the dominant chord.
