Espelhos das (In)tolerâncias. Marcílio Onofre. Cello. Extended Techniques
This research deals with the collaborative process between composer / interpreter in the composition and interpretation of the work "Espelhos das (In)tolerâncias” of the composer Marcílio Onofre, commissioned by Rodolpho Borges. We will deal here with the problematic related to some peculiar aspects of the work such as, for example, the different scordatures, the use of the multiphonics and the tonlos. This work approaches and analyzes the construction of the piece as a whole, not only in the solo cello part, but in the totality of the voices composing the piece, in this way it highlights the main points where the collaboration actually takes place and its purpose is to demonstrate the dynamics of this process, where and when the interpret assists in the construction of the piece, suggesting and proposing feasible solutions, sharing his technical instrumental knowledge and allowing the composer all the technical field in the creation of the piece for the cello. As a methodological procedure, authors such as L. Cardassi (2016), C. Domenici (2012) and F. Borém (1994), who deal with the composer-interpreter relation were studied at a first moment, and six interviews and meetings between the composer and the interpreter, as well as rehearsals, recordings and public performances of the piece. At the finish of this process, we conclude that this partnership provides different technical and musical possibilities for composers and performers.
