Abstract:

In the field of computer music, melodic based forms of vocalizations have often been used as channels to access subject’s queries and retrieve information from music databases. In this study, we look at percussive forms of vocalizations in order to retrieve rhythmic models entrained by subjects in Samba culture. By analyzing recordings of vocal percussions collected from randomly selected Brazilian subjects, we aim at comparing emergent rhythmic structures with the current knowledge about Samba music forms. The database of recordings was processed using a psychoacoustically inspired auditory model and further displayed on loudness and onset images. The analyses of emergent rhythmic patterns show intriguing similarities with the findings in previous studies in the field and put different perspectives on the use of vocal forms in music information retrieval and musicology.
