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.
