The ability to judge PITCH absolutely, without reference to another pitch or frequency. Also called absolute pitch. Perfect pitch appears to be an innate ability of some individuals, whereas related skills, such as remembered pitch or relative pitch which use other pitches as references, can be learned through musical practice.
Musical INTERVAL recognition can also be learned through ear training exercises. Compare: EAR CLEANING.
Compare: CONCERT PITCH, DIFFERENTIAL THRESHOLD, INTONATION, TUNING. See reference to chroma under PITCH.
