Re: Anyone want to discuss NEGATIVE HARMONY/musical palindromes/compositional polarit
Well, I don’t think the nomenclature Negative Harmony was a thing until Jacob Collier coined the phrase, but I think it’s been in use for some time.
Modern pop music is all about melody, particularly the vocal melody, so harmonization rarely comes into play.
I also think this is just starting to sink down out of the Intelligensia now, thanks to streaming culture and social media, so it may not appear in popular music for some time. For myself I am using it to reharmonize mono sequencer lines. The piece I am working on is in Em, which would have it’s mirror in Eb Lydian depending on how you transpose it. The way I am using it is not as a modulation or a key change, but mirroring melody lines from G Major to D Negative Major.
When I have a working demo I will post it here.
Yes, negative harmony was not the term I learned. I'm not sure I learned a particular name for it, as I was taught about it as an aspect of symmetrical tonal organisation in general. Musical palindromes were certainly spoken of, but there are many other ways to form musical palindromes than negative harmony, so I think we used the term in a broader way. As far as the term goes, it seems to be slightly older than Collier, though: the term was used in Ernst Levy's
Theory of Harmony, which was pushumously published in 1985; that is, nine years before Collier was born.
The roots of the concept go way back, though. The first possible predecessor I am aware of is the French composer Jean-Philippe Rameau (1683–1764), who coined the term "subdominant": If one visualizes the dominant as being five steps above the tonic, the subdominant is likewise five steps below. In classical music, applications of the principle can be found in practice from ca 1900, so as an idea, it isn't exactly novel, but it is right that it hasn't really been used much, if at all, in popular music. The use of chromatically inverted melodies, which really seems to be at the root of what you are suggesting, is a significant part of Schoenberg's serialism, and finding examples at least in the inter-war period should be easy. I will go out on a limb and guess that there must be examples even in Debussy.
I look forward to hearing your experiment, though, because I don't think I am aware of the concept being used in a popular idiom.
