The sonic universe of Acusmatrix is constructed upon digital transformations of birdsong of 4 european species: Capercaillie (Tetrao Urogallus),   Rock ptarmigan (lagopus mutts), Eurasian blackcap (Silvia Atricapilla),  and Little grebe (Tachybaptus Ruficollis). Acusmatrix presents a sound generation method with a tree structure. Starting with an original bird sound,  the transformations produce successive metamorphosis of the original, creating a genealogy of perceptually interconnected sounds with multiple junctions and branches. Why choose birds? Birds are probably the most stunning sound virtuosos over the planet, and their repertoire covers a great spectromorphological range of absolute contemporaneity, moving between noise and delicate pitched tones. The sections (each one developing particular transformations of a particular bird) of the piece are
