Only major and minor chords may be tonicized. Diminished chords and augmented chords cannot be tonicized because they do not represent stable key areas in Western music. For example, a B minor chord (B, D, F#) occurring in any of its closely related keys may be tonicized with an F# major chord (V/V) because B minor also represents a key area—the key of B minor. However, a B diminished chord (B, D, F) may not be tonicized because "B diminished" could not be a stable key area; there is no key area in Western classical music that has B, D, & F—the pitches that make up the B diminished chord—as the first, third and fifth scale degrees, respectively. This holds true of all diminished and augmented chords.
