Perceptual evaluation of music similarity

This paper presents an empirical method for assessing music similarity on a set of stimuli using triadic comparisons in a balanced incomplete block design. We first evaluated the consistency of subjects in their rankings and then the concordance across subjects. The concordance was also evaluated for different subject populations to assess the influence of experience of the subject with the musical material. We finally analysed subjects’ ranking by the means of multidimensional scaling. Similarity judgments were found to be rather concordant across subjects. Significant differences between musicians and non-musicians and between subjects being familiar or non-familiar with the music were found for a small number of cases. Multidimensional scaling reveals a proximity of songs belonging to the same genre, congruent with the idea of genre being a perceptual dimension in subjects’ similarity ranking.
