Resumo
In this research we address multiphonics sounds in bassoon. Our objective was to
investigate technical support for the performance of Cantares para Airton Barbosa by Aylton
Escobar, because the lack of knowledge about the technique for the emission of these sounds
precludes this performance. We conducted primarily a bibliographic study of methods that
address the technique for issuing multiphonics sounds. Later we proceeded a technical and
interpretive study of Escobar's work, based on studies of the previous phase. Finally, our goal
was to diagnose the real technical extensions required for the issue of multiphonics. For this, we
compared the instructions for fingering, embouchure and air pressure of Weissenborn´s method
1887, the reference to traditional bassoon technique, with the instructions found on modern
methods, which address the multiphonics, as the methods of Bartolozzi (1967), Penazzi (1971),
Gallois (2009) and Sampson (2004). After conducting this research, we concluded that the
materials presented here, provide sufficient technical support for the performance of multiphonics
present in Cantares. However, we observed different results in different types of materials, which
shows the need to test by the performer. We also conclude that for the issue of multiphonics
sounds there were technical extensions fingering, at the mouth and in the field of air pressure in
relation to the Weissenborn instructions for the performance of the bassoon.
