Pitch as Property

The relative height of a sound, ranging from low to high. A pitched sound will contain relatively focused spectral energy, and it is this characteristic that enables pitched sounds to be distinguished from noisy sounds (see Noise).

Pitch as Sound Type

Objects that vibrate in a more ordered fashion produce sounds that we describe as pitched. This is because the sounds produced contain a greater focus of sound wave energy, with frequencies concentrated into narrow bands. These concentrations of sound wave energy at certain frequencies are called partials.
