The results reported here suggest that the relative contribution of different harmonics to the perception of pitch is not fully hard wired but is—to a certain degree—plastic. While the effect of context reported here is small, it is consistent with previous reports showing that the relative contribution of individual harmonics to residue pitch depends on duration (Gockel et al. 2005a, 2007). The relative precision of the internal representation of the frequencies of different harmonics changes with duration, and it appears that each harmonic is weighted according to the precision of that internal representation.
