Why do minor chords sound “sad” and major chords sound “happy”?

Question

This doesn’t make any sense to me, these are just sounds, they don’t sound neither happy nor sad to me (when I try playing them on piano). But I’m new to music so I don’t know… Is there an explanation that actually makes sense?

Answer 1

The major 6th chord sounds happy and resolved and is a mainstay of pop, jazz, blues, and boogie. It is an inversion of the relative minor 7th chord. In C the notes are C E G A, the same notes as the Am7 chord.

So to answer your question, I have no clue.
