Post-prepared Piano Animated Sequence

I put together this animated sequence of the media from Post-prepared Piano to illustrate the relationships between the spectral analysis, the mapping with nails and twine, and the music from the piece. Thanks to Photosounder developer Michel Rouzic for suggesting that I make a video combining the sound and imagery after seeing the documentation I posted a few days ago.

Chromatic Currents II

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 I

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.
