The Decibel John Cage Variations app guides performers through a realisation of the complete John Cage Variations. It generates a series of animated and standard graphic notation scores in real time that allow the works to be easily interpreted while staying true to the aleatoric nature of the originals. The app can be networked between multiple iPads for use by an ensemble. (For more information, see http://www.decibelnewmusic.com/the-complete-john-cage-variations-project.html) The app is designed to be used in conjunction with Cage's scores, and is released in conjunction with the John Cage Trust and Peter's Edition.
