Why do major scales sound happy? Why is minor sad?

unless you're Fiona Apple lmaooo

>When you think you know what you're talking about

It'd be C Eb G, not D#, brainlet. Same notes, huge difference.
And only one note is shifted down a half step.
The minor third makes it minor, the perfect fifth is the same in minor/major.
If they were both minor you'd have diminished.

this too bassically.
>tense =/= sad
guy never made that equivalence. but that simplicity is associated with pleasantness, and viceversa, which is right.

in fact id solve the tense/sad issue with the following: tense and sad are both adjectives that can describe minor chords or other complex harmonies. id say what tense and sad have in common is introspection, so maybe major makes us explore the exterior and feel expansive in its simplicity, while minor, diminished and other stuff makes us more aware of our internal states, which are never a single mood or emotion, but a complex interwoven system. ever seen a kid listen to music thats too weird or dissonant? they just switch and fuck off, or feel a bit scared. adults on the other hand actually feel sad or start recalling stuff that happened in their lives which they match to the sounds heard, hence why sad ballads are massively popular.

harmonic overtones is the clue btw.

youre so boring
