Comprendre l harmonie négative pour enrichir une progression harmonique et ré harmoniser une mélodie
Understanding Negative Harmony
Introduction to Negative Harmony
- The tutorial aims to explain negative harmony, its purpose, and how it can enrich harmonic progressions and melodies.
Key Concepts of Negative Harmony
- Negative harmony allows for chord substitution, enhancing musical compositions by replacing chords with others that maintain the same functional role.
Active and Stable Notes in a Key
- Active notes are those requiring resolution between chords, while stable notes do not need resolution.
- In C major, stable notes include C (1st degree), E (3rd degree), and G (5th degree).
- Active notes include B (7th degree), A (6th degree), F (4th degree), and D (2nd degree).
Dominant 7th Chord Analysis
- The dominant 7th chord built on G in C major is G-B-D-F, which contains both stable and active notes essential for tonal music.
Movement of Active Notes
- In a perfect cadence from G dominant 7th to C major, active notes resolve: F goes down to E, D can go either up or down to C, B resolves up to C.
Exploring the Chromatic Cycle
Structure of the Chromatic Cycle
- An octave consists of 12 chromatic keys divided into two groups; this structure is crucial for understanding negative harmony.
Correspondence Between Notes
- Each note in the top group corresponds vertically with a note in the bottom group; e.g., C corresponds with G.
Applying Negative Harmony to Chords
Transforming Major Triads
- When applying negative harmony to the C major triad (C-E-G), it transforms into a C minor triad (G-Eb-C).
Example with Dominant Chord
- The G major triad becomes an F minor triad when applying negative harmony: G-B-D transforms into C-Ab-F.
Implementing Negative Harmony in Progressions
Chord Progression Example: Anatole
- The Anatole progression in C major includes chords based on degrees: I-C, vi-A minor, ii-D minor, V-G.
Substituting Chords within Progression
- In this example, A minor becomes Eb major and G major becomes F minor through negative harmony application.
