Some speaker are suspended on a plexiglass support by metal cables secured to metal supports. The different arrangement of the speaker creates a very dense and structured environment that returns an audio composition. The latter is achieved by using sounds that are produced mathematically based on the length of the cables that hold the speakers. The length of each cable , is translated into wavelength and subsequently in frequency which, inserted inside synthesis algorithms realize the sound material . This sound material , is then assembled compositionally . In this way take part a logical - mathematical consistency between visual appearance and sound of the work mediated by a composition choice.
