My college roommate thinks that hip hop and rap are not music because they do not follow the patterns of western music theory, and thus cannot be plotted out on a music chart. Because the music is repetitive and generally lacks melody, it is defined as "boring" which is a music theory term. Instead of being music, he defines it as "urban poetry". Certainly rap can be poetry, but its poetry over music. I don't agree with any of his theories, and I think it is an extremely limiting definition of music that discounts not only hip hop, but many other genres of music. I may not know much about music theory, but as an avid listener I have a hard time accepting these dated rules and notions, and I'd like to hear your thoughts.
