Sound is a mechanical vibration (eg, as produced by a vibrating piano string). This vibration sets up small oscillations of air molecules that, in turn, cause adjacent molecules to oscillate as the sound propagates away from its source. Sound is called a pressure wave because when the molecules of air come closer together, the pressure increases (compression); as they move further apart, the pressure decreases (rarefaction).
