 absolute pitch (ap), widely referred to as perfect pitch, is a rare auditory phenomenon characterized by the ability of a person to identify or re-create a given musical note without the benefit of a reference tone. pdf document ap can be demonstrated via linguistic labeling ("naming" a note), auditory imagery, or sensorimotor responses. for example, an ap possessor can accurately reproduce a heard tone on their musical instrument without "hunting" for the correct pitch. researchers estimate the occurrence of ap to be 1 in 10,000 people. generally, absolute pitch implies some or all of the following abilities, achieved without a reference tone: * identify by name individual pitches (e.g. a, b, c) played on various instruments. * name the key of a given piece of tonal music. * reproduce a piece of tonal music in the correct key days after hearing it. * identify and name all the tones of a given chord or other tonal mass. * accurately sing a named pitch. * name the pitches of common everyday sounds such as car horns and alarms. people may have absolute pitch along with the ability of relative pitch, and relative and absolute pitch work together in actual musical listening and practice, but strategies in using each skill vary.{{cite journal |first=ken
