From "Cosmic Pulses":
In KLANG (SOUND), The 24 Hours of the Day, the 13th Hour is entitled COSMIC PULSES
(Electronic Music).
24 melodic loops, each of which has a different number of pitches between 1 and 24, rotate in
24 tempi between 240 and 1.17 rotations per minute in 24 registers within a range of circa 7 octaves.
They are successively layered on top of each other from low to high and from the slowest to the fastest
tempo and end one after another in the same order.
The loops were enlivened by manual regulation of the accelerandi and ritardandi around the respective
tempo, and by quite narrow glissandi upwards and downwards around the original melodies. This
was carried out by Kathinka Pasveer according to the score (see the form scheme).
What is completely new for me is the new kind of spatialisation: each section of each of the
24 layers has its own spatial motion between 8 loudspeakers, which means that I had to compose
241 different trajectories in space. That sounds very technical – and it is.
For the first time, I have tried out superimposing 24 layers of sound, as if I had to compose the orbits
of 24 moons or 24 planets (for example, the planet Saturn has 48 moons).
For making this possible, I am grateful to Joachim Haas and Gregorio Karman, collaborators in the
Experimental Studio for Acoustic Art in Freiburg.
The loops and the synchronisation were realised by my collaborator Antonio Pérez Abellán.
If it is possible to hear everything, I do not yet know. In any case, the experiment is extremely
fascinating!
