In the days before telescopes we could only see five planets, which we communicated with via the pentatonic scale, adding the earth, moon and sun gives the octave whilst the twelve tones represent the months of the year.
During the renaissance, after Galileo was the first to publicise the existence of planets around Jupiter, a massive political debate erupted over what the correct tuning of the twelve notes should be. Pythagorean modal scales based on the natural numbers were altered to the well-tempered scale we now find on the piano. By the twentieth century, Stockhausen, Miles, Hendrix and Train, not to mention Peter Maxwell Davis were struggling with the vastness of the new universe we had unveiled.
Today light pollution obscures all but the brightest stars and NASA has a monopoly on communicating with the galaxies and the solar federation.
Is it any wonder we are at war.
