Le Jour et la Nuit is a sequence of 176 short pieces for flute, fixed media and live electronics, composed using algorithmic composition procedures to relate music to 176 aphorisms written by the French cubist painter Georges Braque, collected in the book Le jour et la nuit. Cahiers: 1917-1952 (Gallimard, Paris 1952). Eight different forms of notation have been formalized, associated with each piece in relation to a linguistic density parameter. All the musical parameters of the composition, as well as the electronics ones, are likewise related to linguistic, formal and / or structural aspects of the corresponding aphorism. The different notations also represent different degrees of opening of the pieces. Performance. A Le Jour et la Nuit performance should consist of a free choice of the number and order of the pieces to be performed. As well as a book of aphorisms, this work is meant to be a collection from wich to extract the desired pieces: the criteria of this choice are left to the performers, and under no circumstances a progressive order performance should be encouraged. A performance of only “A” notation pieces is not allowed; at least one piece with “D” notation must be performed. Le Jour et la Nuit A/V may also be presented either as an audiovisual stand alone work or an audiovisual electroacoustic performance, in wich "D" notation pieces are accompanied by a found-footage video fixed media. Flute: Claudia Giottoli, Andrea Biagini, Giovanni Petrini, Sara Valle, Denise Tamburi.
