In jazz harmony, chromatic alteration is either the addition of notes not in the scale or expansion of a progression by adding extra non-diatonic chords. For example, "A C major scale with an added D note, for instance, is a chromatically altered scale" while, "one bar of Cmaj7 moving to Fmaj7 in the next bar can be chromatically altered by adding the ii and V of Fmaj7 on the second two beats of bar" one. Techniques include the ii-V-I turnaround, as well as movement by half-step or minor third.
