Chromatic Currents Part I

Here’s a segment of sound from another GMS video I produced yesterday called Chromatic Currents. Once again I was letting the visuals drive the piece, while I controlled parameters in the GMS. On Sound Globules I used the circle of fourths with probability distributions so that C was the most frequent note followed by F, Bb, Eb and so on. I really liked the rare dissonant pitch making its way into the sequence, so I tried a similar technique for Chromatic Currents. The scale was strongly C minor pentatonic, weighted with the 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 stream of notes. The possibility of having any note within a chromatic scale occur in the stream led me to the title.
