please delete if not physicsy enough for the PF. I have always wondered why music sounds musical. there is general agreement through the music charts that a wide range people all agree on what a good song is evidently. generalising above that, nearly everyone agrees regardless of the song/genre/personal taste what qualifies as music and what is just sounds, is there ANY science on this??? more generally being born in the west I like most everyone that does not even play an instrument can keep time with about every song in our typically 4/4 (regardless of speed/tempo) structure we have been cultured into, evidence by head-banging or foot tapping etc listening to eg traditional Chinese or Indian music I can not keep time or figure any of it out to make it sound "musical". my search terms did not pick up anything relevant to my query. thoughts?
