  Work Details  
  SEELEWASCHEN was composed for a light installation by Rainer Gottemeier which is swimming in a huge water bassin of a former shipyard. The environment is surrounded by 7 loudspeakers which are standing in wide distance from each other. Each loudspeaker is acting as an autonomous source playing pre-composed soundfiles and pause tracks in random order. By this, an unexpected sonic situation is created which never repeats itself and always appears in the state of flow and change. The sound material for this piece was drawn from a single stroke of a church bell. By the aid of computer programs which the author has written in MaxMSP, three different structural types (DRONES, STROKES, TEXTURES) have been composed: * DRONES: sustained sounds with slow fade-in and fade-out (exploring the technique of „granular synthesis“) which appear in 7 different transpositions. Those transpositions are based on an all-interval-row; the manifold combinations of its intervals are creating the basic harmonic structure in which the entire piece is embedded. * STROKES: isolated bell strokes with long sustain, in 7 different transpositions (see above). * TEXTURES: rapidly changing transposition of the church sound using very high overtones relationships which result in a rich texture that ressembles the sound of birds. Pre-composed variants of those three sound structures and a set of carefully measured pauses are combined by chance operations which are carried out autonomously by each loudspeaker. Indoor version IRCAM (Paris): October 2004 SEELEWASCHEN („Purification de l’âme“) is a multi-channel sound environment which was originally composed by Karlheinz Essl for an outdoor light installation by the German artist Rainer Gottemeier. Using the sound of one single bell stroke as its basic material, the piece unfolds a rich sonic cosmos by a computer program written in Max/MSP. By using random-controlled algorithms from the composers Realtime Composition Library (RTC-Lib), the piece is generated in realtime. It can be perceived as a sonic organism which might serve as a source for inspiration and meditation. For RESONANCE 2004, a new version of the original piece was created to be presented in a closed space. Accessed 10.12.06 from http://www.essl.at
