While most of all the other emotions have an evolutionary reason to be there, I don't see why do we like humor and music. Why are those feelings there? I'm not asking anyone "why do you like music", it's obvious that everyone likes music because of its melody/rhythm. My question is a purely scientifical one - why do some combinations of tones sound good?
Also, if someone happens to know that: can psychopaths (I'm talking about the medical condition) enjoy music/humor?
P.S. Also, hello everyone.
