VIDEO: RUHR 2010 European Capital of Culture, Rhein-Herne-Canal (2010)

Description

The artist placed three sound sources into the landscape and played large spaces the canal landscape. Two of the sound sources faced each other on the canal: The compression air horns near the cement pumps on one side of the canal and the M-Pipes, a Brane, compression air horns, and compression air pipes on the other. The third sound location was mobile. A switcher of the Wanner-Herner-Railroad transported the instruments over a distance of 1.5 kilometers.

Copper-Horns (2010)
PDF

A horn group consists of 64 horns, small, modified ship’s horns. 32 horns have copper bells whose sound color is reminiscent of trumpets. Each wind machine is powered by a portable air compressor of the type used in road construction with a minimum pressure of 7 bar or 100 psi (pounds per square inch) and an air flow capacity of 1.000 to 2000 CFM (cubic feet per minute), These units have an operating dBA as low as 64 db which significantly reduces the incidence of unwanted noise. The ship’s horns are tuned diatonically and are controlled by a computer.

Materials: steel, copper
Weight:
Dimensions: length 220cm [=7.2 feet] x width 80cm [=2.6 feet] x height 140cm [=4.6 feet]

Helix-Horns (1989)
PDF

The development of the sound generator for the Helix Horns took several attempts, the last and best solution was the “Zetfon,” the sound generator for a classic ship’s horn produced by the Zöllner Company and which was adapted for the Helix Horn.

There are eight Helix Horns in different sizes and fundamental notes, each fitted with its own electrical pneumatic sound generator. A specially constructed MIDI-control allows each Helix Horn to play several notes and their overtones.

Materials: steel sheets which galvanized in a silvery sheen
Weight: 110 kg
Dimensions: several sizes; the more slender design is 3.50 meters [=11.5 ft.] high, has a total length of 12 meters.

Specially built nozzles enhance the blow noises of the air stream, the tone appears rough. Drainpipe tubing is mounted to sixteen valves, the controllable air stream generates strong sounds.

Material: steel, pipes, 8 gas valves, 300 mBar blower
Weight: 145 kg
Dimensions: height 200cm [=6.6 ft] x length 200cm [=6.6 ft] x width 350cm [=11.5 ft]

Brane (2010)
PDF

Each Brane consists of a membrane, which is vibrated bij an air stream movingover a circular mounting. Brane's acoustic color and pitch level is determined by the sounds occurring at the end of a tube. Schläger bundled sixteen Branes and mounted them - similar to Kulong and Typedrum - on a ring at a height of 3.40 meters.

Material: steel profiles, rubber membranes, valve block
Weight: 120 kg
Dimensions: length 460cm [15.1 ft] x height 340cm [=11.2 ft]
