The purpose of music is to incite feelings.
Music has power to affect the hearers and raise feelings and passions in human beings.
In fact, not just raise these passions independently, but raise them one after another in a single piece of music. The King of Denmark once asked a musician if he could excite any passion. When he answered yes, the king commanded a trial. Sure enough the monarch was soon in actual tears. But not all modern music is able incite such passions.
