Notes on Modal Interchange and Cush Chords

Introduction

• Discussion on popular chords: 1-4-5 in C major.
• Not all impactful songs use this progression; they mix major and minor chords.
• Focus on creating emotional impact through modal interchange.

What is Modal Interchange?

• Definition: Combining chords from different modes to enhance emotional depth.
• Chords in C Major:
  • C, D minor, E minor, F, G, A minor, B diminished
• Chords in C Natural Minor (C Aeolian):
  • C minor, D minor, E flat major, F minor, G minor, A flat major, B flat major
• Benefit: Expands chord choices from 7 to 14.

Examples of Modal Interchange

Narlos Barkley

• Example of using C minor with chords like:
  • C minor, E flat major, A flat major, G major
• Impactful moment: Mixing C major with A flat major from C minor.

Claude Debussy - Claire de Lune

• Key: D-flat major
• Key moment in the piece:
  • A-flat 7 (5 chord)
  • Use of E major (borrowed from D-flat minor) for emotional effect.

Hall and Oates - I Can't Go for That (No Can Do)

• Starts with F minor 9, transitioning to C minor.
• Contrast between dark (F minor) and light (C major) creates emotional depth.

Practicing Modal Interchange

• Concept: Using parallel modes to create interesting compositions.
• Basic Progression Example: C major (I), D minor (ii), A minor (vi), G7 (V).
• Practice Steps:
  • Swap chords with C Aeolian
  • Explore new tensions and colors in progressions.
• Other modes to explore: Phrygian, Dorian, etc.

Cush Chord Game

• Developed as a fun way to explore modal interchange.
• Key Concept: Use a major key’s structure but borrow chords from its relative minor or other modes.
• Example:
  • Using chords from E-flat with C as the tonic for a different sound.

Conclusion

• Cush Chords: Name derived from a casual conversation about creating a mellow sound.
• Encourage creativity and experimenting with different chord progressions.
• Invite feedback and suggestions for other chord progressions to try.
