Sonority Analysis of Ressonâncias by Marisa Rezende: A Performance-Based Approach

Abstract

In this paper, we present a sonority analysis of a work by Marisa Rezende, Ressonâncias (1983) where the main goal was to include performative elements in the analysis. First, we identified the key elements of sonority construction in the performance of the piece, which are: use of pedal, use of register, and piano touch. Given these key elements, an analysis was performed by applying Guigue’s (2011) concepts in respect to sonority analysis, verifying the elements through data obtained from a recording of the piece which was performed on piano by the first author of this paper. The material analyzed consists of MIDI and audio data, having extracted information as to velocity, Q values, spectral centroid and spectrogram. The preliminary results of this experimental methodology showed that including the performance in a musical analysis is a valid possibility.
