The Clavilux 2000 is an interactive instrument for generative music visualization, which is able to generate a live visualization of any music played on a digital piano. The setting of the installation consists of three parts: A digital piano with 88 keys and midi output, a computer running a vvvv patch and a vertical projection above the keyboard.
For every note played on the keyboard a new visual element appears in form of a stripe, which follows in its dimensions, position and speed the way the particular key was stroke. Colours give the viewer and listener an impression of the harmonic relations: Each key has it’s own color scheme and “wrong” notes stand out in contrasting colors.
Fasinating, no?
