The Wasserturm Prenzlauer Berg is Berlin’s oldest water tower, completed in 1877 and in use until 1952. The structure was designed by Henry Gill and built by the English Waterworks Company. It is situated between Knaackstraße and Belforter Straße in Kollwitzkiez, in the Prenzlauer Berg locality of Berlin (part of Pankow district) and worked on the principle of using piped water to supply the rapidly growing population of workers.

An adjacent machine hall was the first concentration camp in Nazi Germany in the first half of 1933.

For bavarian whip crackers, reverberation and timeframe

Two whip crackers follow a score to be executed in the Water Reservoir of Berlin, Prenzlauerberg, exploring the acoustic qualities of the architectonic construction though a direct interaction with reverberation. The sound emitted by the cracks, its velocity, amplitude and timbral qualities serve as materials to establish a dialog between the performers and the acoustic qualities of the location.

The Water Reservoir of Kollowitzplatz in Berlin-Prenzlauerberg is used as an exponential amplifier by adding rotating mechanisms to its architectonic structure. Exploring acoustic phenomena such as refraction, reflection and diffraction, the location transforms in a resonant chamber, approaching it as an instrument with unique acoustic properties. This, due to the resonant qualities of the construction in which ~18 seconds echo can be experienced inside the water tower.

The sound emitted by the cracking of a leather whip is used as acoustic exciter. This acoustic phenomenon is produced when a section of the whip moves faster than the speed of sound, creating a small sonic boom. This was confirmed in 1958 by analysing a high-speed shadow photography taken in 1927, testifying that the tip of the whip moves twice as fast at the loop of the whip, just like the top of a car’s wheel moves twice as fast as the car itself.

As an extension of this action, a series of photographs will be produced. Analysing the physical properties and complexities of the whip in motion.
