Tunnel Divisions is a sound installation/ music composition by Stephen Trothen and Cayley MacArthur

This recording was made March 28, 2014 in the underground tunnel connecting South Campus Hall to Arts Lecture Hall at the University of Waterloo between 12:00pm and 4:00pm.

Video Footage: youtu.be/mIJdzluVPlk

The piece utilizes 5 PIR sensors, an Arduino microcontroller, Max/ MSP and Ableton Live.

The 5 sensors are used to divide an underground tunnel into four measures of music.

Individuals moving through the tunnel trigger piano notes, the output of which is divided into two sets of speakers.

The speed with which individuals move from one sensor to the next determines both the tempo of the subdivisions of notes, as well as the complexity of the note phrases, and the scheduling of key changes.

The left and right audio channels are positioned at opposite ends of the tunnel, and rhythmically echo each other across different octaves and playing dynamics.

The output of the piece is generative and of indeterminate length.

This piece was created in collaboration with the Critical Media Lab.
