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.
All stripes stay and overlap each other in an additive way, so at the end a kind of pattern remains – a summary of the music – which will be always unique since the notes of the composition aswell as the interpretation of the piano player are influencing the outcome. Furthermore the piano player can switch between the standart 2d view and an additional 3d view of the visualization while playing.
