What is music?

My name is O'Brian Davis and I am interested to know what others consider music. It is my belief that participating in this class, philosophy of music, will provide such answers. The thought that comes to mind when thinking of music is that it is a sequence of sounds. But what kind of sounds? Do others have similar views? Or, is music simply based on your perception. Is it predetermined? Is music free from boundaries - does it have to be organized? Can noise be considered music? What are the characteristics of music? These are the questions that I seek answers for.
