Abstract

This work presents a study about the computer as an instrument for musical performance. Based on this study we developed processes of music creation using the algorithmic representation and the computer code. The two main technical resources we applied in our works were: a sound synthesis method based on the generation of waveforms by non-linear equations; and methods for music information retrieval to provide a computer memory of the music parameters in real time. The dissertation has the following structure: first, we show the characteristics of the digital music instruments and the consequences of its using in the musical practice. Second, we review the state of the art of music information retrieval area and we detail the specific methods we used in our works, which include: a) the extraction of music parameters from monophonic audio signals captured from acustic instruments; b) analysis of the dynamic behavior of measurements extracted from audio signal, by means of Poincaré maps. Next, we present the sound synthesis method by non-linear equations. Finally, we show the musical creative process we developed based on our studies (AU)
