A tuba’s notes are lower pitched than a flute’s, but the fuzz from an untuned radio has no discernible pitch. Pitch is an attribute in virtue of which sounds that possess it can be ordered from “low” to “high”. Given how audition works, physics has taught us that frequency determines what pitch a sound auditorily appears to have. A theory of sounds must address the audible qualities. What exactly is pitch, and how is it related to the physical property of frequency? Given psychophysical evidence which indicates that there is neither a linear nor a logarithmic function from the frequency of a sound to the pitch listeners experience it to have, auditory researchers have adopted the view that pitch is a subjective or psychological property. That is, pitches strictly only belong to **Authors:** [[Casey O’Callaghan]]
