ODD (2006) 10:35″ Acousmatic 5.1 Multichannel Piece

Commissioned by the DAAD for the Inventionen 2006 Festival, ODD was conceived based on the SMS tools, which are a set of techniques and software implementations for the analysis, transformation and synthesis of musical sounds, developed by Xavier Serra an his team at MTG (Music Technology Group). The textures of the piece are built from “residual” components which after a process of constant transpositions create very dense no-pitch sound masses. In a sense, ODD is a trio, having three recognizable sound sources, a violin, a set of percussions and a female voice, which are surrounded and interrupted by this residual, permanently moving textures. The spacialization of sound was founded on the geometrical concept of odd functions that are symmetric with respect to the origin, meaning that its graph remains unchanged after rotation of 180 degrees about the origin. The work´s structure is based on four clear moments defined mainly by its background sonic textures, in its internal construction it is also the result of selecting graphic information given by the SMS analysis and subjectively interpret it as a “score” of the incoming musical events. ODD used the SMS tools as a “prism” that can disperse a “light” (sound) wave.
