Earth Trilogy

The tonic notes, the tempi and also the length of the three tracks are calculated from our planet's three elements of motion, in exact accordance with the law of the octave. Unusually, the frequencies of each note on the synthesizer are altered in such a way that the scales of notes are tuned exactly diatonically - that is to say, in each case exactly according to the natural overtones. 1.1 based on earth's rotation around the sun. 63,8 bpm. blue-green. 136,10 hertz. 1.2 based on the daily earth rotation. 91,4 bpm. red-orange. 194,18 hertz. 2.1 based on the platonic year of the earth. 80,7 bpm. red-violet. 172,06 hertz.
