DESCRIPTION:
ALBA MUNDI, The sound of Solar System

The earth - and with it, each of the planets of the solar system - revolving around the sun makes a musical note so low it cannot be heard by the human ear.
If we imagine a piano keyboard without limitation, the sound of the earth is a "C sharp" placed 29 octaves below middle C (about 4.7 meters left of the piano bench)
The piece called "Alba Mundi" is composed with the tonality of the earth and the harmony of the piece is made by using the nine notes of the solar system planets as the bass notes.
Mercury - the closest planet to the sun is also running a "C sharp" with its orbit - passing to the orbit of Venus (which runs the note "A"), to continue with the Earth (C sharp ), Mars (D), Jupiter (F sharp), Saturn (D), Uranus (G sharp), Neptune (G sharp) and Pluto (C sharp). At the end of the piece, after the final crescendo you can listen to the "sound" of the solar system, accelerated by more than 68 billion times in order to be audible to the human ear.
The recording of the piece "Alba Mundi"- composed and performed by Giorgio Costantini - was masterized by Alex Wharton (who has worked for Coldplay, Bjork, Gorillaz) at the Abbey Road studios in London
