Problem:
I am sure many of us know the feeling of that tingling chill down our spines when listening to certain music.
I experienced this most when my younger brother played an emotional piano piece for a talent show (brought me to tears).
Required:
Question 1: What causes that?
Question 2: Is music the only stimulus to elicit that spine-tingling?
Question 3: And in terms of evolution, why?
Explain thoroughly.
