Music wiki:
>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.

note wiki:
usic">music, a note is either a unit of fixed pitch that has been given a name, or the graphic representation of that pitch in a notation system, and sometimes its duration, or a specific instance of either, so one can speak of "the second note of Happy Birthday" for example. The general and specific meanings are freely mixed by musicians, although they can be initially confusing: "the first two notes of Happy Birthday are the same note", meaning, "the first two sounds of Happy Birthday have the same pitch." A note is a discretization of musical or sound phenomena and thus facilitates musical analysis (Nattiez 1990, p.81n9).
