Music has been around for thousands and thousands of years. The caveman had originally started some type of sounds in which branched off into the music that we listen to today. This prehistoric music was started by the cavemen in order for them to express themselves, and the others who listened were affected in the same way that people are affected by music today. For example, if someone is upset they will listen to something that will get them into a better mood, perhaps something mellow or soft. If they are happy, they will listen to something that is more...
or a fraternity party, you will see people expressing themselves.

Music can also cause a lot of problems too, like the ones I mentioned above. People need to respect it for that quality because it is able to affect people in every way imaginable. It is hard to explain exactly why humans love music the way they do, but it is an art form that we have been creating since the dawn of man. We will continue to explore the wonders of music and explore new ways to produce it while being affected by it at the same time.
