Very common it seems for songs to change keys into a higher one but I dont think I’ve really ever heard something doing a descending modulation or key change…
closest I can think of is Strawberry Fields by The Beatles but my understanding is that is Varispeed or something, not really sure what the heck is happening in that song other then its gradually flattening but not sure what that even is
Utterly fascinating! Thank you so much for this :)
Also I was super unclear and did an edit so no worries about it, I often revise when my perspective or knowledgebase changes so its nothing on you, I just like to tweak things as I go along
