Fades/Costellazioni is a work of sound designed to be exhibited in a dedicated space. It is to be considered like a sculpture, a painting, or as architecture. It has been realised in the form of a web application, to listen to it you need an internet connection and a stereo audio system.
Fades/Costellazioni appears as a continuous process of slow cross-fades between harmonic structures created with electronic sounds carefully tuned to each other. It has no beginning or end, its duration coincides with the time of contemplation. The evolution of the process is regulated by combinatory logics which ensure that, even within a homogeneous language, it never repeats itself in the same way.

The sound installation is accompanied by the score of the work, a 200 pages 18x27cm book printed in 100 numbered copies. The score was inspired by the notation system for just intonation invented by the Mexican-American music theorist Erv Wilson. The 1/1 root note is an A at 432 Hertz located in the center of the lattice.
The sounds are generated electronically with sinusoidal oscillators.

Fades/Costellazioni is ideally designed for a quiet space. It is not suitable for either outdoor or headphone listening. The quality of the audio system significantly affects the aesthetic result; I recommend the use of a subwoofer. The score is an integral and indivisable part of the work.
