Desta forma podemos aprofundar o estudo em processos composicionais, aqui restrito ao universo criativo do celebre chorao brasileiro.

Starting from the hypothesis that the musical elements within Brazilian musical genre Choro are arranged in a hierarchical way (ZISELS; AVELLAR; ALMADA, 2014), this dissertation explores the possibility of systematizing compositional practice within the genre. Which, in turn, serves as a theoretical frame for the exploration of different levels of structural importance. This research is comprised of both descriptive and statistical analyses. The descriptive approach is used in order to split key musical domains into smaller fragments. The statistical analysis addresses to the investigation of elements that fulfill either structural or superficial functions. In parallel, the probability data from a detailed examination of 19 Choros – a total of 57 independent parts – are used for a purpose-built software specifically constructed for algorithmic composition. We discuss the domains of rhythm and contour separately, before cross-referencing them for the purpose of producing a workable model. The formalism of the rhythmic domain is based on the assimilation of the concept of inter-onset interval (TEMPERLEY, 2001). The contour domain is systematized using the contour gestures approach, which is an appropriation of a methodological treatment of Jay Dowling (1978). The statistical data for each domain are carefully explored and a discussion of structural differences is proposed. The dissertation concludes with a detailed description of the compositional modeling process. The results are discussed and both the analysis and modeling point to promising paths for the continuation of the research.
