In
music alteration, an example of
chromaticism, is the use of a neighboring pitch in the
chromatic scale in place of its
diatonic neighbor such as in an
altered chord. This should not be confused with borrowing (as in
borrowed chord), in which pitches or chords from the
parallel key are used in place of those of the original key. Altered notes may be used as
leading tones to emphasize their diatonic neighbors.
For example, an altered
dominant or V chord may be Gb-B-D#:
