sound and noise

I loved that when first reading this article the author made a clear distinction between sound and noise- he said that when music first began the goal was a harmonious composition that would soothe the ears. However, the introduction of Futurist music changed that, it became a composition of noise and different sounds, not meant for a melody. The example shown in class of "music" left me in disbelief that noises like that could even be called music. But after reading this article and learning the new movement that has emerged from this I understand that the sequence and gradation and tone of the noises does make this in a way music.
