Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale,<ref>Anssi Klapuri, "Introduction to Music Transcription", in Signal Processing Methods for Music Transcription, edited by Anssi Klapuri and Manuel Davy, 1–20 (New York: Springer, 2006): p. 8. ISBN 978-0-387-30667-4.</ref> or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies.<ref> {{#invoke:citation/CS1|citation |CitationClass=book }}</ref> Pitch can only be determined in sounds that have a frequency that is clear and stable enough to distinguish from noise.<ref>Harold S. Powers, "Melody", The Harvard Dictionary of Music, fourth edition, edited by Don Michael Randel, 499–502 (Cambridge: Belknap Press for Harvard University Press, 2003) ISBN 978-0-674-01163-2. "Melody: In the most general case, a coherent succession of pitches. Here pitch means a stretch of sound whose frequency is clear and stable enough to be heard as not noise; succession means that several pitches occur; and coherent means that the succession of pitches is accepted as belonging together" (p. 499).</ref> Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre.<ref> {{#invoke:citation/CS1|citation |CitationClass=book }}</ref>

Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system.<ref name=hartmann>{{#invoke:citation/CS1|citation |CitationClass=book }}</ref>
