Pitch is the perceptual property ordering sounds from low to high

Evidence

Pitch is defined by the American National Standards Institute as ‘that auditory attribute of sound according to which sounds can be ordered on a scale from low to high’ (ANSI-S1.1, 2013). Pitch is perceived from many types of sounds, such as sinusoids, vocals, instrument sounds, and noisy sounds (Fastl and Zwicker, 2007; Hartmann, 1996). However, the definition is problematic in the sense that not all sounds have clear pitch, and some of them have more than one pitch. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1075
