Modulation from D-flat major to F-flat major using a mixture chord in Db major (bVI6) as a pivot chord.Ĭonversely, we can use diatonic chords in the old key as mixture chords in the new key to modulate to distant keys in the “sharpwise” direction on the circle of fifth. Modulation from A major to F major using a mixture chord in A major (iv) as a pivot chord.Įxample 4. Example 4 shows this technique being used by Verdi in his opera Rigoletto.Įxample 3. Shared chords between C major and E-flat major, made possible through mode mixture.Įxample 3 shows a modulation from the key of A major to F major, using iv from A major as a pivot chord. Example 2 shows the common chords shared between C major and E-flat major, made possible by using mixture chords in C major.Įxample 2. those chords found in C minor, its parallel key), we can now modulate easily to E-flat major (7 shared chords), A-flat major (4 shared chords), B-flat major (3 shared chords), and their relative minor keys, F minor and G minor. For example, in the key of C major, the chords made possible through mode mixture (i.e. Mode mixture enables us to expand the number of possible pivot chords for modulation. To modulate to a distantly-related key, that is, a key that is more than one accidental away on the circle of fifths, requires us to use our knowledge of chromatic chords, such as those found through mode mixture. When two keys are more than one accidental apart on the circle of fifths, however, it becomes more difficult it is to find a pivot chord that will enable a smooth modulation between the two keys. For example: Example 1: Common chords in the keys of C and G major Modulation to closely-related keys is a relatively easy task we can find a pivot chord by looking at the group of chords shared between two keys that have nearly-identical key signatures.
