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. / Nesta pesquisa abordamos sons multifônicos ao fagote. Nosso objetivo foi investigar e discutir subsídios técnicos para a performance da obra Cantares para Airton Barbosa do compositor Aylton Escobar, pois o desconhecimento sobre a técnica para a emissão desses sons impossibilita esta performance. Realizamos primeiramente um estudo bibliográfico envolvendo métodos que abordam a técnica para a emissão dos sons multifônicos. Posteriormente procedemos um estudo técnico-interpretativo da obra de Escobar, fundamentado nos estudos da fase anterior. Por fim, nosso objetivo foi diagnosticar as reais extensões técnicas requeridas para a emissão dos multifônicos. Para isso, comparamos as instruções relativas a dedilhado, embocadura e pressão de ar, do método de Julius Weissenborn, de 1887, referência da técnica tradicional do fagote, com as instruções encontradas nos materiais modernos que abordam os multifônicos, como em Bartolozzi (1967), Penazzi (1971), Gallois 2009 e Sampson (2014). Após a realização dessa pesquisa, pudemos concluir que os materiais apresentados aqui, oferecem subsídios técnicos suficientes para a performance dos multifônicos presentes em Cantares. Porém, observou-se diferentes resultados em diferentes tipos de materiais, o que mostra a necessidade de testes por parte do performer. Concluímos também que para a emissão dos sons multifônicos houveram extensões técnicas no dedilhado, na embocadura e no domínio da pressão do ar, em relação às instruções de Weissenborn para a performance do fagote.
