Gustav Mahler: Symphony No. 5, 4th Movement, Adagietto

Music of the Spheres is an old and much-discussed concept, still, no one has probably used planets as actual instruments before. The electromechanical organs work in such way that small metallic wheels turn really fast (for example 440 times per second) in front of an electromagnet, thus producing an electric sine curve whose magnified sound we can hear over the speaker. Planets rotate around the Sun – e.g., the Earth completes its round once a year. In order for us to hear that sound, the Earth would need to rotate around the Sun at least twenty times per second. For each second of the sound, the calculations made with the help of the NASA database offered almost 50,000 daily astrology charts and positions of the planets. Using the sine trigonometric function, this data can be transformed into digital curves. As the route of the planets deviates considerably from an ideal circle, the digital curves aren’t proper sine curves. Each of the planets has its own, somewhat eccentric circumference, and therefore also a unique sound. These sine curves are then played at different speeds so that we can get – from a musical point of view – an appropriate pitch of the sound wave (approximately 100,000 faster than real time).

Stepping in for the double basses, three frequency modulated oscillators played the Earth (the heliocentric curve of the Earth is a mirror image of the geocentric curve of the Sun), for the cellos, we used Venus and for violas, a combination of the Sun and Venus was utilized. Only the first violin combined the Sun and Venus with the geocentric Moon, and the second violin also used Mercury. All of this perfectly “destabilizes” the system and gives it a “softer”, more organic sound.

All the sounds are additionally modulated with a 42-minute recording of signals from six EEG electrodes. The recording was made two years ago while measuring an emotional response of a member of the audience watching the theater performance A Melancholic Croquis. The oscillation in the conductivity of human skin co-creates a sound landscape of the environment where a digital simulation of the outer space chimes in sound
