I like to nerd out on Rick Beato videos This one has me wondering about what constitutes "modern" harmony I generally analyze harmony in terms of functional "roman numeral" harmony i.e, diatonic chords, cadences, secondary dominants, tritone substitutions. even when the chords get "weird" I look for fragments of familiar V - I motion. I tend to assume the "weird" notes are voice leading. This helps me grasp a sense of structure and navigate the song and (along with stylistic understanding) guides my bass line choices. As far as I can tell "modern" harmony seems to just chuck everything out the window except voice leading. Is there more to it? Are there some overarching common patterns or approaches out there? or is modern harmony just a mash up of arbitrary techniques?
