The power of music
Music is a very powerful tool to express one's feeling on a topic. It can sometimes convey a message better than normal words can. It can also help someone better understand the message. A good example of an instance of when music was a powerful tool was with the old Native Americans who would sing and dance to prey to the gods for something to happen, like rain. This was a very special ritual to them. Another example is when someone wills make a song out of something to help a student remember a school subject, like all the schoolhouse rock songs and the song to help people remember the quadratic formula in math.
