Sounds are produced by movements in the air. Planet movements cannot be heard, but you can at least simulate these waves by MIDI- instruments.

Wolfgang Martin STROH (Research Project of the University of Oldenburg, Germany) has built a computerbased program to convert the actual constellation of the planets into frequences, rhythms and patterns you can make audible. Each planet has it own fundamental (frequence of the moon = 52,605 Hz) and its own metrum (metrum of the moon is 95,5 ).

With his MIDI-planetarium W. STROH delivers a program to produce a cosmic simulation of the planet sounds.

Spherical music today isn't harmonic at all in terms of Pythagoras or Kepler. Cosmic music only allows to have a musical impression of the planetary harmony. Developping a computer tool to convert individual horoscopes into individual music pieces, Stroh will be researching the holistic integration of the human being (micro cosmic world) in the planetary system (macro cosmic world). He didn't estimate it as a personal finger-print, but listening to personalized music pieces, 79 % of the subjects of his experiment recognize characteristics of his personality.

Originally developed on Atari ST, Midi-planetarium is now available as PC- version (GM) and on CD-ROM.

On a concert evening a computer calculates from position and movements of the planets fundamentals and overtones at the moment of the concert. In interaction with the music computer an overtone improvisor (voice, didjeridu, aquaphone, tampura) conducts the audience into the meditative music of the macro cosmos.

2002: Wolfgang Martin Stroh's Algorithmic package is about 27 programs for Atari ST: they are all available FOR FREE at http://tamw.atari-users.net/algo.htm thanks to Tim CONRARDY's efforts and ... mine.
