Solo bassoon; Musical composition; Extended techniques; Multiphonics
This research deals with the use of multiphonics in the work Reflexões for solo bassoon by the composer Agamenon de Morais Junior, based on an approach to preparation for performance. Considering that there are few pieces that contemplate the study of extended bassoon techniques during a collaborative composition and the desire to change this reality. Thus, the objective of the research was to record the process of choosing multiphonics, as well as the learning and performance procedures on the bassoon. The precepts involving the use of multiphonics are based on Bartolozzi (1967), Souza (2016), Gallois (2008), Oliveira (2013), and Penazzi (1971). As a result of this work, a cycle of compositions for solo bassoon was obtained, exploring extended techniques; a suggestion for categorizing multiphonics, a proposal for studies to master multiphonics and, finally, the audiovisual record of the study of the work and the premiere of the piece.
