Common Patterns of Secondary Dominants in Pop Music Progressions

by

Secondary dominants are a fundamental aspect of pop music harmony, adding color and tension to chord progressions. They are chords that temporarily tonicize a chord other than the tonic, creating a sense of movement and surprise for the listener.

Understanding Secondary Dominants

A secondary dominant is typically a major or dominant seventh chord that resolves to a diatonic chord other than the tonic. It is often notated as V/X, where X is the target chord. For example, V/ii is a dominant chord that resolves to the ii chord.

Common Patterns in Pop Progressions

Pop music frequently employs specific secondary dominant patterns to create engaging progressions. Some of the most common patterns include:

  • V/ii to ii: A dominant chord leading to the ii chord, often used to introduce a minor ii chord.
  • V/IV to IV: Adds tension before resolving to the IV chord, common in ballads and chorus progressions.
  • V/V to V: Creates a quick tension-release cycle, emphasizing the V chord.
  • V/vi to vi: Used to highlight the minor vi chord, often in pop ballads.

Many hit songs utilize secondary dominants to enrich their harmonic language. For example:

  • “Let It Be” by The Beatles: Uses secondary dominants to lead into minor chords, adding emotional depth.
  • “Someone Like You” by Adele: Employs secondary dominants to emphasize poignant moments.
  • “Shape of You” by Ed Sheeran: Incorporates secondary dominants in its chord progression to maintain interest.

Harmonic Function and Voice Leading

Secondary dominants function as temporary V chords, creating a sense of expectation. Proper voice leading involves resolving the dominant seventh or major chord smoothly into the target chord, often by stepwise motion or common tones. This technique enhances the seamless flow of the progression.

Conclusion

Understanding and utilizing secondary dominants allows pop composers and songwriters to craft more compelling and dynamic progressions. Recognizing these patterns can also aid students in analyzing and appreciating the harmonic complexity of their favorite songs.
