Chromatic Textures, by Unearthed Music, is “a study on the synesthetic nature of our senses of sound and sight.”
Video input is used to produce generative musical phrases. The visual media is analyzed by the GMS (Gestural Music Sequencer) to create the musical forms in real-time.
The software includes adjustable probability distribution maps for the scale and rhythm. Adjusting these settings allows familiar structures to emerge. The settings chosen for this piece cause notes within a particular scale to play more frequently, however, it is still possible for any note within the twelve-tone chromatic system to occur. As a result, dissonant or blue notes can be heard at rare instances throughout the piece.
The Gestural Music Sequencer is a free app for Mac & Windows.
