Teoria dos contornos aplicada: composição da peça "Em forma de feitiço" a partir do samba urbano carioca dos anos 1930

Abstract

The Theory of Musical Contour has increasingly been applied in Brazil and has also been known as an important tool for musical analysis and composition. In this paper, the application of the theory on the compositional process went through as a guideline for musical cohesion and coherence. Its concepts and premises had a role in guiding the composition of a piece for flute, clarinet, cello, basson and percussion, entitled Em Forma de Feitiço. This piece presents musical material generated from melodic and duration contours extracted from two well known songs that represent this rythm in the way we know it nowadays. Starting from such contours from popular music, it was possible, through operations based on the Theory of Musical Contour, to generate melodic elements for the composition, as well as vertical resultants, respecting the voice leading guided by the contours chosen. It was possible to observe, during the development of this paper, various possibilities that the Theory of Musical Contour can provide to a compositional process, knowing, however, that there is still much to be explored.
