Secondary Dominance: Incorporating a chord from another key into a chord progression.
Objective: Understanding how to identify and use secondary dominant chords in a progression.
Functional Harmony Basics
Chords in Key of C: Illustrated with a diagram, each associated with Roman numerals.
5 Chord: G in the key of C, called the 'dominant' chord.
In functional harmony, the 5 chord typically resolves to a 1 chord.
Example in Key of G
In the key of G:
5 Chord: D, which resolves to G (5-1 progression).
Constructing a Chord Progression
Common Progression: In key of C - 1, 4, 5, 1 (C, F, G, C)
Introduction of Secondary Dominant:
From key of G, incorporate D before G in the key of C.
5 of 5: Use the 5 chord of the 5 chord in key of G (D) before G in key of C.
This creates a 5-1 resolution from another key within the key of C.
Expanding with Secondary Dominants
Beyond 5 of 5: Can use 5 of other scale degrees (e.g., 5 of 2, 5 of 6).
Example - 5 of 6:
Target the 6 chord in key of C (A minor).
5 Chord in A minor: E
Use E as secondary dominant in C major.
Progression Example: 1 -> 5 of 6 -> 6 -> 5 -> 1
Usage in Minor Keys
Application of secondary dominants in minor keys (e.g., 5 of flat 3).
Multiple secondary dominants can be used in a progression.
Enhancing with Dominant 7th Chords
Dominant 7th Chords: Adding a 7th to a secondary dominant chord can enhance sound.
Example: E chord becomes E dominant 7 in 5 of 6 progression.
