This second part to “Chromatic Currents” was produced with the GMS by using a string of lights placed into a large glass vase. I moved the camera around the vase to direct the flow of musical phrases with one hand while I adjusted transposition and note duration settings in the sequencer with my right.
You might notice that the video stimulus does not resemble lights in a vase. This is because I applied a negative filter to the video after capturing the performance. I used a pentatonic scale interspersed with rare dissonant notes and probability distributions in the note durations to give it an eerie awkwardness.

Chromatic Currents Part I is a generative music piece driven by particles floating in a liquid. No intervention in particle behavior occurred while the piece was being performed using the GMS. The scale was strongly C minor pentatonic, weighted with a Dorian mode by adding less-likely probabilities for D and A. However, every note that was not part of the scale still had a small possibility of occurring. This led to occasional blue or dissonant pitches in the sequence. The possibility of occurrences for any note within a twelve tone chromatic scale led me to the title.
