This Jazz Piano Tutorial is about reharmonisation.
Reharmonisation is a fancy word for chord substitution but for the whole chord progression rather than just an individual chord.
It is used to make a song more ‘jazzy’, that is more harmonically and/or structurally complex; and personalise a song and make it your own (it’s almost like composing a brand new song, or a variation of an existing song)
So, generally, a song consists of:
- Melody
- Chord progression
Reharmonisation involves changing the melody or chords or both – but changing them with regard to certain rules or ideas.
To reharmonise a song you need to take two things into account:
1. Harmony
- Interaction between melody and chords
- Depends on quality of chord (Maj, min, Dominant, etc.)
- Goal: Melody note is an ‘Acceptable Harmony’ over the chord
2. Structure
- Movement of chords & bassline
- Not affected by quality of chord
- Goal: Structure must be logical
So the overarching goal in a reharmonisation is to:
- Change chords and/or melody to ensure the melody is an ‘acceptable harmony’ over the chord
- Change chords and bassline so they move in ‘structured way’
Following the concepts, ideas and rules in this video will allow you to create a strong and professional reharmonisation.
