Lesson 37 Enharmonic Modulation with German Sixths

Lesson 37: Enharmonic Modulation using German Sixths.

Part I

Enharmonic modulation takes advantage of a common chord spelled differently in two separate key signatures. For example, in C Major, the V⁷ Chord is spelled: G, B, D, F. At the same time, the Gr^{6 chord in B Major is spelled E#, G, B, D,} 

^Listen:

Part II - Using the Gr⁶ and V⁷ to modulate 

In this example, The point of modulation is the V⁷ chord in C Major (Which is also the Gr⁶ chord in F# minor). 

Listen:

Part III - Modulation using secondary dominants

The Secondary Dominant of any chord in any key can also function as the Gr⁶ in another key. Notice how the V⁷/IV in C Major is the same as the Gr⁶ in E minor.

Listen:

The point of modulation is a V⁷/V in C Major and an enharmonic Gr⁶ in the ending key of E minor.
