>For other uses, see Music (disambiguation). Music is a natural intuitive phenomenon operating in the three worlds of time, pitch, energy, and under the three distinct and interrelated organization structures of rhythm, harmony, and melody. Since the music phenomenon is natural and intuitive, humans can also virtually perform and hear music in their minds, without even learning or understanding it.Traditionally, one of the major difficulties in defining music has been to use the word to try to describe all activities and things related to music and/or sound. For example, scores only become music through performance(s), or when (recorded) performances are replayed. See more at Wikipedia.org...
