Based on Russolo’s ” The Art of Noises”, he defined what noise was by comparing from the past to the present. He stated how noise used to be very primitive; a silent and remote sound that could be heard simply from the street outside. Now, he described noise as something that is very loud and prolific due to advanced technology such as machinery. A machine such as a bull dozer to a mechanical pencil sharpener are two different tools yet they produce two very distinctive sounds. Even one’s footsteps create sounds that can be heard. One aspect that Russolo wanted to emphasize was music. Music is an extension of noise that is organized by tones and rhythms to create a sense of emotional response to the listener. He used the term Musical Noise that creates bigger, acoustic sounds with high quality and variety. He stated.” We must break at all costs from this restrictive circle of pure sounds and conquer the infinite variety of noise sounds”. He wanted the break the silent noise and branch it out to create a variety of different sounds and tones . However, we are not capable of doing that alone. Machinery is a broad term that he keep repeating throughout the article so instead he chose to use the word instrument. An instrument is a tool that helps produce sounds and in order to create music, we need to form an orchestra. Symphony is an elaborate composition for an orchestra; musicians work together to create music through a variety of diverse instruments. It is a combination of machinery and noise to alter the pitches and tunes . Eventually, we will be able to distinguish over three thousand sounds.

I can hear different instruments being used like a trumpet or a triangle . The change of pitch changes throughout.
