ELI5: Why aren't all sounds "music"? How is it that we perceive some as melodic but most are just noise?

It's mostly because of how humans recognize patterns. There's tons of atonal music where there is no key that is followed, but there's still patterns there.

Whenever you hear a fan making white noise, there's a pitch there, but you might not find a pattern. Some abstract music might not be considered music by this logic, but that goes deeper than your eli5.
