"The heavenly motions... are nothing but a continuous song for several voices, perceived not by the ear but by the intellect, a figured music which sets landmarks in the immeasurable flow of time." John Banville: Kepler, (Minerva 1990)
In line with the philosophical idea of harmony of the spheres I have created Earth Songs

The philosophical concept of the Music of the Spheres has been around for a long time. The Harmony of the Spheres di not necessarily relate to the audibility of the sounds the planets made but more that it was an element of philosophy, mathematics and religion. Ancient philosophers perceived the planets, their alignment and movements to express various answers to the why of their world. Recently with the use of powerful sound transmitters NASA has recorded the audible songs of planets which are both haunting and mysterious. These sound raise more questions rather than provide answers.
