A Teoria dos Contornos aplicada na Fusão Paramétrica do Frevo de Rua Pernambucano: inter-relações com aspectos da Música de Concerto do séc. XX

Abstract

The main objective of this thesis is to decipher the possibilities of developing compositional plans based on the study of the fusion of elements of street frevos from Pernambuco with aspects of 20th-century concert music, in addition to the elaboration and description of original compositions resulting from these plans. The manipulations of the parametric elements of frevo music were based on analytical procedures, such as the Theory of Contours, Joseph Straus' Revisionary Proportions and the textural relationships between register, absolute and relative densities, redefined by Wallace Berry and improved by Didier Guigue. The thesis also demonstrates how various concepts such as sound masses, micropolyphony, serialism, minimalism, metric modulation, etc., were appropriated by the planning and how such planning structured the compositional actions that resulted in four pieces: a brass quintet (Creation No. 3), an orchestral composition (Scenes for Orchestra) and two pieces for percussion ensemble (Frevindo-Serializando and Frevindo-Minimalismando). The second part of the thesis contains the scores of these compositions.
