The categorical perception of pitch by musicians [e.g., W. Siegel and R. Sopo, J. Acoust. Soc. Am.57, 511 (1975)] raises an interesting question: How can they tune their instruments when they cannot tellsharpfromflat? Here, the results of two experiments on ELP, a musician with very fine absolute pitch, suggest a resolution of the categorization paradox. In a production task, which emulates tuning an instrument, he was very accurate at adjusting the frequency of an oscillator to a value corresponding to four musical notes, g♯ (415 Hz), a (440), c (523), and d♯ (622). However, in an identification task involving listening to single brief notes, he showed striking evidence of categorical perception. That is, he judged 400‐, 500‐, and 600‐Hz tones to be accurate examples of the notes g♯ (415), c (523), and d♯ (622) on most of the trials.
