Noise (radio) in the context of "Thermal noise"

A definition of music endeavors to give an accurate and concise explanation of music's basic attributes or essential nature and it involves a process of defining what is meant by the term music. Many authorities have suggested definitions, but defining music turns out to be more difficult than might first be imagined, and there is ongoing debate. A number of explanations start with the notion of music as organized sound, but they also highlight that this is perhaps too broad a definition and cite examples of organized sound that are not defined as music, such as human speech and sounds found in both natural and industrial environments. The problem of defining music is further complicated by the influence of culture in music cognition.

The Concise Oxford Dictionary defines music as "the art of combining vocal or instrumental sounds (or both) to produce beauty of form, harmony, and expression of emotion". However, some music genres, such as noise music and musique concrète, challenge these ideas by using sounds not widely considered as musical, beautiful or harmonious, like randomly produced electronic distortion, feedback, static, cacophony, and sounds produced using compositional processes which utilize indeterminacy.
