Introduction
Reharmonization is the art of transforming the harmony of a musical piece to give it new life and different emotions. It’s like reinterpreting a familiar story from a fresh and personal perspective. Great composers like Bach, Mozart, Coltrane and Bill Evans have used this technique to create works that transcend generations. Now you have the tools to do the same! This skill allows you to express your unique musical voice while working with melodies you love. 🎵
Main Concept
Reharmonizing means modifying the original chord progression to create a new sonic palette without altering the melodic essence. Think of it as changing the lighting on a painting: the subject remains the same, but the atmosphere changes completely. 🎨
To reharmonize effectively, you must first master the tonal functions of each degree:
| Degree | Tonal Function | Emotional Character |
|---|---|---|
| I | Tonic | Stability, rest |
| II | Supertonic | Smooth movement |
| III | Mediant | Moderate tension |
| IV | Subdominant | Expansion, departure |
| V | Dominant | Maximum tension, preparation |
| VI | Submediant | Softness, nostalgia |
| VII | Leading tone | Urgency, direction |
Key Reharmonization Techniques
Diatonic Substitution: Replace a chord with another from the same tonality that fulfills a similar function. This maintains tonal coherence while adding subtle variety.
Secondary Dominant Substitution: Use secondary dominants to create movement toward chords that are not the original V. This adds impetus and harmonic direction.
Chord Interpolation: Add chords between diatonic movements to enrich the texture and create smoother transitions.
Modal Exploration: Recontextualize the melody using different modes. Each mode offers a unique emotional character:
| Mode | Emotional Character |
|---|---|
| Lydian | Bright, dreamy, suspended |
| Mixolydian | Bluesy, energetic, rock/gospel flavor |
| Phrygian | Exotic, dramatic, flamenco flavor |
💡 Balance: The best reharmonizations dance between respect for tonal functions and creative daring. Respect the rules when learning fundamentals and maintaining tonal coherence, but break them when creating deliberate tension or expressing your personal style.
Examples
Example 1: Diatonic Substitution
- Original: I - IV - V - I
- Reharmonized: I - III - V - I
- Result: Greater dramatic tension by introducing the III as a bridge to the V
Example 2: Secondary Dominant Substitution
- Original: I - II - V - I
- Reharmonized: I - V/II - II - V - I
- Result: Greater impetus and harmonic direction through added chromatic movement
Example 3: Modal Exploration - Miles Davis, “So What”
- Mode used: Dorian (Phrygian in the second section)
- Result: Innovative and emotionally deep sound that defined an era of jazz 🎷
- This demonstrates how modal recontextualization can completely transform a melody’s emotional impact
Practical Summary
Here’s how to start developing your personal harmonic language:
| Step | Action | Focus |
|---|---|---|
| 1 | Start Simple | Take I-VI-II-V and make just one change |
| 2 | Listen and Feel | Play original vs. reharmonized - compare emotions |
| 3 | Document Discoveries | Note what worked - your vocabulary is growing |
| 4 | Experiment in Context | Apply to real melodies you know well |
| 5 | Challenge Yourself | Reharmonize one melody in three different ways |
