How does a music of the planets composition originate?

Sonification“ („sound made audible“) is the presentation of data referring to events in sounds.

In order to understand what I hear I have to realize the data.

Data that forms the basis of Akustik-Clock are Ephemeris.

Ephemeris are charts which contain moving astronomical bodies in constant intervals.

In an narrow sense these are charts of positions of sun, moon, planets.

Ephemeris for the observant astronomy use either the full circle of 360 degrees alongside the ecliptic or specify the position in equatorial coordinates.

Ecliptic (latin: lineaecliptica ‘to the eclipse’s belonging line’; greek: ekleipsis ‘failing to appear, disappear, darkness’) is the seeming orbit of the sun in a year’s course in front of the fixed star’s background. Watched in geocentric projection from the earth ecliptic forms an imaginary great circle on the celestial globe.

Akustik-Clock is the perpetual interval of 1 day and uses the full circle alongside the ecliptic – that is to say zodiac.

Location of the surveillance is the earth.

That means:

Available is data of sun, moon and planets for every day in terms of 0 to 360 degrees – evaluated from the earth.

One data record contains date (+ time (12.00 GMT) and the information of the position of objects.

Graphically seen this is nothing else than a horoscope pictured by astrologer. Markings of positions of planets are in the zodiac for a specific date.

Planetenmusik – music of the spheres (Audio-CD)

Audio-CD: Planetenmusik / music of the spheres is the cooperation of Brian Cranford, Tobias Krug and Hartmut Warm.



CD-review (click here)


In August 2001 Hartmut Warm published his book „Signature of spheres / Maintenance of order in the solar system“ which is dedicated to the analysis of texture of motion, layout and harmonic connection in our solar system.


In November 2002 Tobias Krug and Brian Cranford started the project „Akustik-Clock“. Here there is the artistic-scholarly debate with the interplanetary rhythms of the solar system.

2006 Brian Cranford established the label „Indiscreet Cosmos Recorder“ and in the same year he published the CD „Akustik-Clock / musical siderale“ a combination of conclusions up to this date.
