CHAPTER 15
Chromatic Alterations
Chords may be chromatically altered. The fifth of a chord is the most frequently altered chord tone. Chromatically altered notes are never doubled.

RAISED FIFTH
The raised fifth may appear on dominant, tonic, and subdominant chord in major keys. The raised fifth (raised supersonic scale degree) of the dominant chord must ascend to the third of the tonic chord. This will result in an acceptable doubled third of the tonic chord in first inversion. The augmented dominant chord may be used in root position or first inversion.

FIGURE 15.1. The Augmented Dominant Chord
The raised fifth (raised dominant scale degree) of the tonic chord must ascend to the submediant scale degree (subdominant or submediant chord). This will result in an acceptable doubled third of the subdominant chord in first inversion. The augmented tonic chord may be used in root position or first inversion when approaching the subdominant chord. It is used only in root position when approaching the submediant chord.

FIGURE 15.2. The Augmented

Tonic Chord

A raised fifth (raised tonic scale degree) of the subdominant chord must ascend to the supersonic scale degree (supersonic or dominant chord). The augmented subdominant chord may be used in root position or first inversion when approaching the dominant chord. It is used only in root position when approaching the supersonic chord.

LOWERED FIFTH
The lowered fifth may appear on the dominant chord; it must descend to the tonic scale degree. The dominant chord with lowered fifth may be used in root position or first inversion.
