Music Theory QuickThink: 

-          A Descending 5th sequence that utilizes secondary dominant chords can be used to modulate to a new key.

-          Example: The chords B7-E-A7-D can be analyzed two different ways. 

-          Use context of what comes before and after to determine if a modulation has taken place


-          The German 6th is an augmented 6th chord that sounds like a Dominant 7th chord (Mm7). 

-          It is not spelled as a Major-minor 7th chord, but the result is enharmonic with a Major-minor 7th

-          The modulation can take place by approaching in one spelling, and resolving as the enharmonic spelling would

-          Example: In the key of Eb Major, an F7 chord is a V7/V (spelled F, A, C, Eb). 


-          Fully diminished seventh chords have the potential to setup modulations by being able to resolve in four different ways, enharmonically

-          Example:

Objective 43.1: Identify and label the following modulations; (1) through Descending Fifth Sequence (2) Enharmonic modulation through Augmented Sixth Chords (3) Enharmonic modulation with diminished Seventh Chords in real music examples
