Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale,〔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.〕 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.〔 〕 Pitch can only be determined in sounds that have a frequency that is clear and stable enough to distinguish from noise.〔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).〕 Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre.〔 〕 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. ==Perception of pitch== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pitch (music)」の詳細全文を読む スポンサード リンク
