The 'Abbauhammer' concert is played with a specially prepared compressed
air instrument set: sixteen dismantling hammers (eight of them with sound
funnels), two hoist-pull motors, two impact wrenches, two baffle plates,
four boiler bottoms, four stamps, four specially built compressed air motor
horns, two pit cage signal bells. The concert is controlled by a "score machine"
built for this purpose and operated by the artist.
Hammerwork consists of four air drums
woth eight pneumatically powered hammers for which the stretched membranes of kevlar -a synthetic
fiber of high tensile strength- over a circular mounting with an internal diameter of 1.50 meters.
Attached to each drum are sixteen hammers each of which are fitted with a pneumatically operated
rotational joint the heads of which covered with various materials, strike the membrans.
The Soundgate concert project is
a whole landscape of unique instruments which realize the "orchestra". The "unvisible" center
of the whole scene are the four gates for this musical "transit". One gate has 32 iron bells
in a circular arrangement. This shape makes it possible to play the bells like a planetary
movement. The total arrangement consists of 290 sound elements intergrate in 20 sound machine
This is a playful connection from improvised music
and composed sequences with the sound machines of Christof Schläger. The main connection is the
natural sound of classical instruments and the pure acoustic sound of the mechanical machine instruments.
It is a meeting between composed moments from the machines and intuitive, fresh responses from the musicians.
Like three little Ufos the 'Klöpperböden'
float in space. On the surface of the objects many incised tongues can be seen. They can be
struck with the fingers and create a floating sound. You can try out the next "UFO" and a small
improvised sound figure unfolds. The sounding tones are free and follow no known scale.
