What is music?

We all hear sounds as we walk down the street, the sound of the cars driving by, the street sweepers, maybe even a baby crying. No one ever thinks of sweeping the street or taking out the trash as music, right? Well what about STOMP, a musical group that uses items such as trash cans and brooms to generate sounds and rhythm? Is this music? (STOMP: BROOMS video) Mark Applebaum also asks this question. His motivation behind what he does it the fact that he gets bored with the music now. So he stretches the meaning of music as he invents his own instruments (Mark Applebaum video). The idea the music is not just sounds but an art and a science will always push innovation and creativity to the modern world.
