An Instrument for Generative Music Visualization
A musical instrument that consists of three parts: 1) a digital piano with 88 keys and midi output, 2) a computer running a vvvv patch and 3) 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 colour the way the particular key was stroke,” notes by the creator Jonas Friedemann Heuer.
Notes by Heuer:
(…) By mapping the color wheel on the circle of fifths, the colours finally give the viewer and listener an impression of the harmonic relations. Notes belonging to one specific tonality always get colors from one specific area of the color wheel. Therefore each key gets it’s own color scheme and “wrong” notes stand out in contrasting colors. The more different tonalities a piece has, the more colorful the visualization will be.
Unlike most other visualized music, the visualization of Clavilux 2000 does not disappear when the music fades away. 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.
(…) Furthermore the system allows the piano player to switch between the standart 2d view and an additional 3d view of the visualization while playing. Also the visibility of a background grid, as [well] as the “deepness” of the 3d view can be adjusted with sliders on the piano.
