Noise in music in the context of Unpitched percussion instrument

Edgard Victor Achille Charles Varèse (French: [ɛdɡaʁ viktɔʁ aʃil ʃaʁl vaʁɛz]; also spelled Edgar; December 22, 1883 – November 6, 1965) was a French and American composer who spent the greater part of his career in the United States. Varèse's music emphasizes timbre and rhythm; he coined the term "organized sound" in reference to his own musical aesthetic. Varèse's conception of music reflected his vision of "sound as living matter" and of "musical space as open rather than bounded". He conceived the elements of his music in terms of "sound-masses", likening their organization to the natural phenomenon of crystallization. Varèse thought that "to stubbornly conditioned ears, anything new in music has always been called noise", and he posed the question, "what is music but organized noises?"

Although his complete surviving works only last about three hours, he has been recognized as an influence by several major composers of the late 20th century. Varèse saw potential in using electronic media for sound production, and his use of new instruments and electronic resources led to his being known as the "Father of Electronic Music"; Henry Miller described him as "The stratospheric Colossus of Sound".

In music production, the recording studio is often treated as a musical instrument when it plays a significant role in the composition of music. Sometimes called "playing the studio", the approach is typically embodied by artists or producers who favor the creative use of studio technology in record production, as opposed to simply documenting live performances in studio. Techniques include the incorporation of non-musical sounds, overdubbing, tape edits, sound synthesis, audio signal processing, and combining segmented performances (takes) into a unified whole.

Composers have exploited the potential of multitrack recording from the time the technology was first introduced. Before the late 1940s, musical recordings were typically created with the idea of presenting a faithful rendition of a real-life performance. Following the advent of three-track tape recorders in the mid-1950s, recording spaces became more accustomed for in-studio composition. By the late 1960s, in-studio composition had become standard practice, and has remained as such into the 21st century.
