1 How many times does the chorus(副歌)repeat in your favorite song?Repetition is a feature that music from cultures around the world tends to share.So,why does music rely so heavily on repetition?2 One part of the answer comes from what psychologists call the mere exposure effect.In short,people tend to prefer things theyve been exposed to before.For example,a song comes on the radio that we dont particularly like,but then we hear the song at the grocery store,at the movie theater and again on the street corner.
