Music and astronomy. VI. Harmonia Mundi 2024

In 2009, Mike Oldfied published his "Music of the Spheres", Depeche Mode their "Sounds of the Universe", and Antonio Arias his "Multiverso", being the last track of his album "Harmonia Mundi 2009". In 1975, Laurie Spiegel composed the version of the Music of the Spheres that started the famous Voyager Golden Record. Almost five decades after Spiegel's sonification and more than four centuries after original Johannes Kepler's Harmonices Mundi, an astrophysicist and two celebrated indie musicians "de Graná" are revisiting the fifth chapter of Kepler's book. Previous versions had focused on the frequency of the planets; however, Kepler's hypothesis was that the sound of each sphere depends on a music interval that is a simple function of the planet's orbit eccentricity. Without leaving Granada, we relate how we are composing this new Harmonices Mundi, Music of the Spheres, Harmony of the Worlds, Musica Universalis, Harmonia tou Kosmou in 2024.
