Polyphonic timbre perception was investigated in a
cross-cultural context wherein Indian and Western
nonmusicians rated short Indian and Western popular
music excerpts (1.5 s, n = 200) on eight bipolar scales.
Intrinsic dimensionality estimation revealed a higher
number of perceptual dimensions in the timbre space
for music from one’s own culture. Factor analyses of
Indian and Western participants’ ratings resulted in
highly similar factor solutions. The acoustic features
that predicted the perceptual dimensions were similar
across the two participant groups. Furthermore, both
the perceptual dimensions and their acoustic correlates
matched closely with the results of a previous study
performed using Western musicians as participants.
Regression analyses revealed relatively well performing
models for the perceptual dimensions. The models displayed
relatively high cross-validation performance.
The findings suggest the presence of universal patterns
in polyphonic timbre perception while demonstrating
the increase of dimensionality of timbre space as a
result of enculturation.

In search of perceptual and acoustical correlates of polyphonic timbre
Alluri, Vinoo; Toiviainen, Petri (2009)Polyphonic timbre refers to the overall timbre mixture of a music signal, or in simple words, the 'global sound' of any piece of music. It has been proven to be an important element for computational categorization according ... -
