I find the major/minor thing so fascinating. I remember it having the "happy"/"sad" vibes from my earliest memories and have a really hard time with the idea that it could be cultural. But if it's not cultural, then why? Also is the fact that major 9ths have a beach/island vibe cultural due to Brazilian jazz? :-)

> have a really hard time with the idea that it could be cultural

I played in a gamelan ensemble in college. The music was completely foreign. A piece that sounded like a funeral procession was played at weddings. I have a hard time believing the arrangement of music is not cultural - or, at least partially culturally bound.

Yeah, that's really getting to the heart of why the idea of a totally objective theory of music seems legit. Major/minor doesn't exist in a vacuum, there's a lot of other signifiers in the music that are highly correlated. It's not just the major triad, it's the energy of the beat, playing, singing, the bright instruments. If you were a 2 year old and just heard a major chord played on a piano, then a minor chord, then you probably wouldn't get "happy" or "sad" from it. Maybe by 3 or 4 you've already picked up the correlation between "happy music" and "major triad". You pick this stuff up really quick and it's part of your core memories/mental model, so it can feel inherent. It's like the fish that doesn't know what water is.

I've been working with some people building a music model from scratch and it really surprises me how much correlation there is across different features. It's been difficult applying that to general sound effects, because music is highly correlated in ways more general sound isn't.

Silly theory for why minor sounds sad: Say "ah", like you've just discovered something interesting. Now say "ah" like you've been told something sad. Notice the pitch difference? And notice how both pitches are about a major third and minor third above normal speaking pitch. Whether that's hard-wired or cultural, I couldn't say. But it would certainly be an interesting thing to research and compare across cultures and musical traditions.

Is "Take Five" sad-sounding even though it's written in a minor key? Maybe it sounds somewhat "cooler", not as bright as a major key piece of the same tempo and energy would be, but it doesn't sound sad.

Metal music is mostly minor.

Does metal sound "sad"? Opinions differ. :)

I play piano. It's not just cultural, it is partly like that checkerboard lighting illusion. What is objectively one shade, can in a different context, seem like the opposite shade. Major and minor keys in classical music can sometimes exhibit this property.
