@@antoniofarina716 Not only do I personally disagree, because to me, relative major and minor are the same key, but the number system shouldn't really have anything to do with key, so - 5-2-6 - b6-b3-b7 - 6-3-7 - b7-4-1 - 7-#4-#1 (or b1-b5-b2, whatever) - 1-5-2 - b2-b6-b3 - 2-6-3 - b3-b7-4 - 3-7-#4 - 4-1-5 - b5-b2-b6 are all perfectly valid names for the progression because they're all mathematically true. All that changed was where the point of reference, the 1, was. But as you can see, 5-2-6 is by far the most efficient name as it has the least alterations, simply because the entire number system is based on the ionian mode, so picking that as your point of reference is the most efficient. And 7-4-1 isn't mathematically true, again it would have to be b7-4-1.
@@antoniofarina716 Only if you assume that "tonic" is equivalent to 1. I just view the number system as a mathematical system that isn't inherently linked to perceived tonality. More importantly, it would be b7-4-1, not 7-4-1. Big difference. But as you can see, viewing it like this adds a flat (actually two since the 4 has to be minor).
Nah... Get ready for more negative harmony covers, for most people, it's just another fun trend in tiktok that allows for a new way to listen to old music
