Composição Musical a partir da Modelagem Sistêmica do Contorno da Complexidade da Textura

Abstract

In this study, we have explored the application of systemic modeling into contour abstractions of musical texture aspects to compose an original set of works. Systemic modeling is a methodology that integrates principles from intertextuality theory and compositional systems theory for musical works examination, aiming to establish a hypothetical generic model with compositional purposes. Our focus was on using the contour of textural complexity as an analytical tool for the String Quartets no. 6 and 17 by Heitor Villa-Lobos, which served as the basis for the Devaneios 4, 5, 7, and 8 works. The main conclusions include evidence of the variety of emergent possibilities in understanding and applying contour abstractions in textural complexity, identification of aspects of Particional analysis that warrant further exploration, and considerations on density-compression. We propose expanding the meaning of the term textural contours to encompass various textural dimensions. Additionally, we highlight the potential of contour of textural complexity modeling in compositional planning, which can contribute to overcoming creative blocks and music composition teaching. Finally, we suggest directions for future research to deepen this field of study, opening up new perspectives for musical analysis and creation.
