Last week, at Casa da Música, I attended the conference “Xperimus: experimentation and Beyond in music” as co-author, in a presentation by Henrique Portovedo on the multiphonics catalogue that we developed, and as author, together with Frederic Cardoso, on the eighth-tone scales I developed for a solo clarinet piece. The presentation was titled “Muffled Sounds on Clarinet: Beyond microtonality and Conventional timbre” and was followed by the performance of the work E é sempre melhor o impreciso que embala do que o certo que basta.
