Edino Krieger’s Sonâncias is considered one of the most representative works of his production for the violin. This article aims to present stylistic, idiomatic and interpretative characteristics in Edino Krieger's writing for his own instrument based on the analysis of Sonâncias II (1981), for violin and piano. After an introduction, we present a biographical summary of the composer (concentrating on his relationship with the violin) and approach the particularities of his musical language and his production for the instrument. Then, we present concepts and criteria used in the structural, stylistic and idiomatic analysis of the selected piece. We examine how this work manifests particularities of Krieger's third compositional phase and how his style and writing influence the interpretive choices in the process of constructing the performance. Considering the experience of the composer as a violinist, we sought to relate his writing to the idiomatic characteristics of the instrument. In Sonâncias II (1981) the intervals (both melodic and harmonic) are used as a basic structural unit. Its idiomatic nature reveals a deep mastery of the composer in writing for the instrument, despite no longer playing it during this process and having abandoned his career as a violinist early in his adulthood. Through this article that constitutes a first approach to Edino Krieger’s writing for the violin we seek to contribute to a better understanding and diffusion of Brazilian music for the instrument.
