Is perfect pitch favored by natural selection?

People with perfect pitch can identify, play, and/or sing a particular musical note without first hearing a reference note. (SF#99 and SF#102) Even if a string of notes is played randomly, they can instantaneously name them. Although musical training while young fosters perfect pitch, the talent also runs in families. A study of 500 musicians, with and without perfect pitch, by N. Freimer at the University of California, revealed that half of those claiming perfect pitch knew family members of like talent. Only 5% of those without perfect pitch made this claim. (Ref. 1)

At the North Shore University Hospital, Manhasset, NY, P.K. Gregersen and M. de Andrade were able to locate 126 perfect-pitchers. In this select group, 5.5% had parents with perfect pitch, and 26% had siblings thus gifted. Among musicians lacking perfect pitch, the figures were 1.1% and 1.3%, respectively. (Ref. 2)

An unexpected (to us, anyway) correlation of perfect pitch and synethesia (SF#68) was made by Freimer's group. Some perfect-pitchers swear they can "see" musical notes, and even "smell" and "taste" them! (Ref. 1)

Comment. Since perfect pitch would seem to be of little use to primitive humans in hunting and gathering, why was it selected for? Likewise, synethesia seems to have little adaptive value; in fact, it might even be detrimental if humans on the brink of survival were confused by exotic sensations.

Quotes

  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W. R., Journal of the Royal Astronomical Society of Canada, Vol. 81, no. 1 (1987), p. 24., 02/1987
