The Chromatic Transformations System in the Interlude from Artémis, by Alberto Nepomuceno

Abstract

This paper presents some theoretical concepts of Riemann and Kopp applied to the structural analysis of the Interlude of Artémis, a lyrical operatic episode composed by Alberto Nepomuceno in 1898. The analytical investigation clarifies that the analytical tool proposed by Kopp—the system of chromatic transformations—fits remarkably well to the studied musical text. The analysis points out that the Interlude of Artémisis was structured with orthodox cadential formulas, although featuring altered chords, which result in the use of expanded tonality. Besides employing this analytical tool, still seldom employed in the study of Brazilian music, this research demonstrates how it helps to understand important technical aspects of the repertoire of the late XIX Century and early XX Century. Its application is particularly elucidative in works of composers who were ahead of their time in respect to the research and use of innovative compositional techniques as chromatic transformations, which belong to the vanguard of their time.
