Music can be define in so many ways, in fact the definition can not be counted and even more are still coming in.

Below are few and the common definitions.

1. Music is the nice combination of sounds and silences.
2. Music is any agreeable sound.
3. Music is an organized sound.
4. Music is the combination of sounds organized to have melody, rhythm, harmony and dynamics
5. Music is the Art or Science of combining vocal or instrumental sounds (or both) to produce harmony and expression of emotion.
6. Music is the combination of pleasant sounds

If you take note from all the definitions, Sound is present. That means Music is all about sounds and silences. Any sound can be music but not every sound is music. That is to say sound can come as Noise or Music. Therefore, when you agree with any organized sound then it is music and when you don’t agree with any sound or sounds, then it is Noise.
