Stockhausen & Elektronische Musik

Spatialization Concepts

Klangmühle

The Klangmühle was an early electronic device for spatialization, allowing the panning between different channels by moving a crank, which was then mapped to multiple variable resistors.

Rotationstisch

The Rotationstisch was used by Karlheinz Stockhausen for his work Kontakte (1958-60) (von Blumroeder, 2018). In the studio, the device was used for producing spatial sound movements on a quadraphonic loudspeaker setup. This was realized with four microphones in a quadratic setup, each pointing towards a loudspeaker in the center:

The predominant effect of the Rotationstisch is amplitude panning, using the directivity of the loudspeaker and wave guide. In addition, the spatialization includes a Doppler shift when rotating the loudspeaker. The rotation device can be moved manually, thus allowing to perform the spatial movements and record them on quadraphonic tape:

Kontakte

Stockhausen's 1958-60 composition Kontakte can be considered a milestone of multichannel music. It exists as a tape-only version, as well as a version for tape and live piano and percussion. For the tape part, the Rotationstisch was used to create the spatial movements - not fully captured in this stereo version (electronics only). Listen to 17'00'' for the most prominent rotation movement in four channels:

Composing within the electronic medium, i. e. modifying sound with the help of electroacoustic apparatuses, has been an essential determinating factor in the musical work of Karlheinz Stockhausen, as a spectrum of electronic pieces from Studie I (1953) to Kontakte (1958-60), Mixtur (1964), Hymnen (1966-67), Oktophonie (1990/91), and Cosmic Pulses (2007) documents. The article considers this seemingly well-known fact from a revised musicological perspective. Considerations from a broader compositional-creative context that include both instrumental and vocal components lead to insights into the origins and history of some of Stockhausen's electronic projects that have found less attention until now.
