Definition
Sound is the perceived complex phenomenon of vibrations traveling as pressure waves through a medium. For all living beings on earth this medium is either air or water. Such vibrations are called sound when they are perceived by (our) hearing.
There are thus three components in sound: vibration, medium, hearing. Generally, silence is considered to be the opposite of sound.

Sound in music
A musical sound can be recognized and defined by its pitch (or frequency), duration (or relative rhythmic value), timbre (color or instrument), dynamics (loudness) and position in space (relative to the listener). All music consists of related sounds and silences, which can be symbolized by notation.
