Ciocca and Darwin [V. Ciocca and C.J. Darwin, J. Acoust. Soc. Am. 105, 2421–2430 (1999)] reported a surprising finding: The shift in residue pitch caused by mistuning a harmonic was the same when the mistuned harmonic was presented after the remainder of the complex as when it was simultaneous. The present study tried to replicate this result, and investigated the role of the presence of the nominally mistuned harmonic in the matching sound. Subjects adjusted a matching sound so that its pitch equaled that of a subsequent 90-ms complex tone (12 harmonics of a 155-Hz F0), whose mistuned (±3%) 3rd harmonic was presented either simultaneously with or after the remainder. In experiment 1, the matching sound was a harmonic complex whose 3rd harmonic was either present or absent. In experiment 2, it was a sinusoid. In experiment 3, the target and matching sound contained non-overlapping harmonics. In all experiments, a non-simultaneous mistuned component produced significantly smaller pitch shifts than a simultaneous one. In the absence of the nominally mistuned harmonic in the matching sound, the pitch shift with simultaneous presentation was about five times larger than that with non-simultaneous presentation of the mistuned component.
