RESUMO

Music has been used in the research of subjective time perception because of its characteristics of temporal structure, as the rhythm, the tempo, the musical accents and others. The combination of these elements during musical listening task excite the activation of attention and memory processes involved in processing of the temporal perception. Due to the diversity of parameters which compose the structure of western erudite music, the use of a multidimensional scaling (MDS) contributed for the research in the musical cognition area once delimits dimensions from a perceptual representation The multidimensional scaling (MDS) comes from a family of analysis techniques of data proximity which is obtained by the participant judgment who compares some objects (stimuli) in some traces (elements), concomitantly. The use of this technique aimed at to identifying dimensions that influenced the subjective time perception during a musical appreciation task. 48 participants (musicians and non-musicians) were listen 16 musical excerpts (20 seconds) of the western erudite repertoire and associate them with the durations of 16, 18, 20, 22 and 24 seconds. Through the MDS a 2 dimensional solution was generated representing the distribution of the musical excerpts in function of the time similarity judgment. A musicology analysis was carried out to evaluate the common musical elements found in the grouped excerpts. It was identified the elements tempo, intensity, timbral density and tension, as much for the musicians as for non musicians. Two complementary dimensions had been identified, 1) tempo and intensity and 2) tension and timbral density for the participants musicians and 1) tempo and intensity and 2) timbral density for the participants non musicians, as responsible for the alteration in the subjective time perception during the appreciation of western erudite music.
