Utopia is the first piece of a series based on Luciano Berio’s Sequenza-series. They can be considered as a tribute to the composer who influenced me as a young composer, while his influence still lasts. In order to create a polyphonic sound experience, the flautist utilises his feet to produce noises. Here it is exactly notated which part of the foot (tip, heel, whole foot) is used in which manner (stomping, scratching). Additionally, the player is challenged by manifold extended techniques: slap tongue, tongue ram, key click, jet whistle, singing and simultaneous playing or multiphonics to name a few. The structure of the piece may be regarded as interwoven. Many smaller form sections that are connected to each other take turns. Additionally, the piece has an electronic layer, it is complemented by my N. 10 (2013) Sýnthesis, a piece of abstract or, respectively, notated electroacoustic music. These two pieces merge, while being connected in a flexible manner. The exact tempo is determined by the flautist. Moreover, the flute is transformed electronically. Apart from so-called bit strokes, the transformation does not change (the same is valid for Sýnthesis). Utopia is an exciting, diverse and conclusive sound adventure.
