"Sequences" was an interactive audiovisual installation during the Berlin Music Week 2013 and was located at the Urban Spree Gallery. It has been developed by Audiodesign students of HdpK Berlin in cooperation with architecture students from Fachhochschule Bern (Switzerland).
The purpose of this installation was bringing together sound and visual elements in a special surrounding with the ability for everybody to manipulate the experience in an interactive way.
The whole sculpture was made out of wooden parts with different sizes and were pieced together to create three vertical circle-like layers, each build on top of the previous one.
By interpreting Terry Riley's famous aleatoric piece "In C" within the context of electronic music, we performed it in a new and unique way. The piece consists of 53 different patterns that are meant to loop by different instruments to a given tempo in a non-predictable way.
Based on the rhythm of each pattern we connected the sound to a light projection to get the rhythm of the lights blinking simultaneously to the music. For this purpose we had set up five LCD-Projectors that were mapped on certain parts of the sculpture that were controlled by different instruments.
Finally, to get the interaction working we used Arduino boards with ultrasonic sensors attached, so we could measure the distance of people walking around. With the resulting data it was e.g. possible to let the people control the tempo of the music or let the lights changing their colour.
