Karlheinz Stockhausen – Cosmic pulses (2007)
Karlheinz Stockhausen – Spiral (1968)

Karlheinz Stockhausen was one of the greatest composers of all time, a tireless innovator right up to his death in 2007. The Tempo Reale project sets out from a great “Stockhausen event” to investigate German electronic music from its origins to the most recent experiences.
The composition Cosmic pulses is part of Klang, a cycle on the 24 hours of the day; it represents the thirteenth hour and uses a totally new technique for the spatialisation of 24 sound layers in 192 computer-programmed tracks.
As the author himself said: “This experiment may be compared to the virtual exploit of synchronising the orbits of 25 planets around a sun, with individual rotations, times and trajectories”.
This very recent work is contrasted with Spiral, a historical work produced in the Sixties for the Osaka Expo: in a large circular space an executor interacts with the sounds coming from a shortwave radio, bringing to life a spectacular performance, utterly free and highly structured musically.
The concert is organised by Tempo Reale, together with BH audio, using a special stage set and a sound diffusion system of great quality and innovation.
