Gilberto Cabral: catalogação de obras, edição e uma abordagem de estudos técnicos das peças Colorido, Sapos, Suíte do Rio Grande do Norte, Maracatchatchu e Sapeca

Abstract

This research started from a survey of works by composer Gilberto Cabral, which resulted in a collection and listing of 26 pieces for trombone in various instrumental formations, which contribute to the diversification and expansion of the trombone repertoire. From this universe, 5 pieces were chosen that represent the total set of work due to their stylistic characteristics. This procedure aimed to identify sections of difficult technical and interpretive execution and from them we proposed studies for the acquisition of skills that allow the performer to perform satisfactorily the works studied. We also make it clear that the study suggestions are based on existing methods for trombone. The works chosen were: Colorido (suite), Sapos, Rio Grande do Norte Suite, Maracatatchu and Sapeca. We also present a biography of the composer that reports from his musical initiation in the state of Pernambuco to his performance in the artistic environment of Rio Grande do Norte, showing his importance and influence in relation to future generations of instrumentalists. Rhythmic and melodic aspects related to the popular manifestations of Rio Grande do Norte were presented through the works, and to discuss them we used several authors as a theoretical reference, among them Cascudo (1984), Costa (2011), Alves (1999). We emphasize the importance of the works for the trombone repertoire and the need to know each one better, since they are based on a language of genres and rhythms of Brazilian popular manifestations, some of which are little known by the general public because they are specific to our region. During the initial survey of the works, we noticed that many of them were already in Finale and Encore format and others in a physical state were already deteriorating, so we proceeded with scanning them in PDF to facilitate access to these materials, in addition to contributing to its preservation.
