Virtual Pitch and Pitch Shifts in Church Bells
It is well established that musical sounds comprising multiple partials with frequencies approximately in the ratio of small integers give rise to a strong sensation of pitch even if the lowest or fundamental partial is missing—the so-called virtual pitch effect. Experiments on thirty test subjects demonstrate that this virtual pitch is shifted significantly by changes in the spacing of the con...
متن کاملVirtual Pitch Extraction from Harmonic Structures by Absolute Pitch Musicians1
The ability of absolute pitch (AP) musicians to identify or produce virtual pitch from harmonic structures without feedback or an external acoustic referent was examined in three experiments. Stimuli con sisted of pure tones, missing fundamental harmonic complexes, or piano notes highpass filtered to remove their fundamental frequency and lower harmonics. Results of Experiment I showed that rel...
متن کاملVirtual pitch in a computational physiological model.
A computational model of nervous activity in the auditory nerve, cochlear nucleus, and inferior colliculus is presented and evaluated in terms of its ability to simulate psychophysically-measured pitch perception. The model has a similar architecture to previous autocorrelation models except that the mathematical operations of autocorrelation are replaced by the combined action of thousands of ...
متن کاملThe oscillatory entrainment of virtual pitch perception
Evidence suggests that synchronized brain oscillations in the low gamma range (around 33 Hz) are involved in the perceptual integration of harmonic complex tones. This process involves the binding of harmonic components into "harmonic templates" - neural structures responsible for pitch coding in the brain. We investigated the hypothesis that oscillatory harmonic binding promotes a change in pi...
متن کاملHarmonic fusion and pitch shifts of mistuned partials
A model is proposed to explain pitch shifts of components mistuned from a harmonic series @W. M. Hartmann and S. L. Doty, ‘‘On the pitches of the components of a complex tone,’’ J. Acoust. Soc. Am. 99, 567–578 ~1996!#. An internal random variable depends on the frequency of the partial and determines both its pitch and the probability that it will fuse within the complex. The model accounts for...
