PÓS-TONALIDADE EM COISA N.2 DE MOACIR SANTOS

This article investigates the Brazilian composer Moacir Santos's creative procedures for Coisa no. 2 (Thing no. 2), a composition from his album Coisas, from 1965. As a musician who combined experience in the popular universe with the study of erudite repertoire, Santos was a distinctive creator of Brazilian music in the 1960s. His economic style merged elements of popular styles, jazz, African percussion and classical influences. Here we focus on his harmonic language, applying tools of neo- Riemannian analysis and set theory, and aim at demonstrating how the artist's harmonic processes helped situate him in the 20th century's post-tonal musical universe.
