"TOOLS FOR DETECTION AND CLASSIFICATION OF PIANO DRUM PATTERNS
FROM CANDOMBE RECORDINGS"
The African-rooted Candombe drumming is one of the most characteristic
traits of Uruguayan culture, and its complex rhythm can sound difficult
to decode for unfamiliar listeners. In this talk we present tools for
detailed analysis of the rhythmic patterns of each type of drum found in
Candombe performances. Given a recording with annotated metrical
structures, the first tool constructs a map of bar-length patterns that
enables the inspection of their evolution over time; the second tool
clusters those patterns, and maps the result onto a low dimensional
space for visualization. Several tests were applied to the analysis of
real piano drum performances as a case study, and the obtained clusters
match characteristic patterns of the instrument, also revealing
differences and similarities among schools or personal styles. The
output of this investigation is an interactive software tool for the
analysis of Candombe recordings oriented towards the study of the
underlying structures and rules governing performance styles and
improvisation.
