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.

Music of our planets in audible signals

Resonance and experimental research

Within the first moments space, range and stillness open up to you. Cascades similar to an organ to the likes of Bach or Messiaen follow. The next composition will remind you of Bach also yet with sounds of a Cembalo. There follow different „instrumentations“, in fact „orchestrations“ and „styles“. Elements of global music or jazz seem to flash, even though it is something completely new and synthetically induced tones. Still amazement and joy from this unexpected sounds linger on.


This cd is the result of long standing teamwork with the following: Hartmut Warm, researcher and author of the book „Signature of Spheres“, Brian Cranford, musician and Tobias Krug, artist. It is intended to transfere the planet’s shifting into music. Warm has analyzed a 2500 years old idea of harmony of spheres. An idea which Kepler crucially renewed 4 centuries ago. Warm examined all this and found himself confirmed in a completely new manner. He evaluated this with elaborate back up equipment. According to that musical intervals with significant compliance – in relation to velocity of the miscellaneous planets -are found in orbit.

In order to conceive what you are listening to it might be helpful to envision an instrument which sounds off exactly then when two planets circulating the sun reach a certain spot. Positions of the celestial bodies are determined either geometrically or by the rate of oscillation. This is transformed to sound.

Respectively six of the well-rehearsed compositions are realized by the method Warm or according to Cranford/Krug. Both are enclosed in the booklet coming with the CD which is quite informative. Joint efforts are that a specific period of time (for instance 1000 years) is pictured – so that cosmic circumstances are chronologically highly compressed. The event appears in different time lapses. Either proportional velocity or the angle between the planets is reset in notes. Although the conversion is a matter of exactly computed positions – reflecting the real planetery motion like a score – there is definitely tolerance for artistic clearance, corresponding approximately with the creation of sound or sound characteristics.

Even if you are not interested in a profound academic background you will take a huge benefit from listening to it. Never heard of rhythms and the chronology change your own rhythm of breathing. „Watching“ of music in relation to ourselves makes it possible to immerse ourselves and as well the range around us.
