However, identifying the pitch of an isolated whistle is beyond the abilities of most people. This is also the case for most musicians, despite the fact that they overhaul every day working in t he context of a interchangeable system of pitch relationships. Those rare individuals who can instantly recognize the pitch of a random piano tone or passing auto horn, without the use of a reference pitch, possess a cognitive efficacy that is termed "absolute pitch."The range of useful musical pitches is 20-5,000 Hz, which is, roughly the range of a piano keyboardPitch is a one-dimensional attribute defined by the number of vibrations, per second, emanating from a sound source, such as a tweak stringThe peripheral auditory organs are designed specifically for frequency analysis. The cochlear basilar membrane vibrates, at each menstruation along its length, with an optimal resonant frequency. The fact that all humans are quick to appreciate the differences in timbre between instruments illustrates the extreme esthesia of this organ to complex frequency spectra.
