Kepler : il cosmo armonico e la musica / Natacha Fabbri.
Abstract:
In his Harmonices Mundi Libri V, Johannes Kepler (Weil der Stadt, Württemberg, 1571 - Regensburg, Bavaria, 1630), besides the formulation of the "harmonic law", expounds the theory according to which the relationships among planetary velocities correspond to musical intervals. In the intellectual paths by which Kepler arrives at his three famous dicta on planetary motion and at his polyphonic cosmos, Platonic and Neo-Platonic traditions assume a central role. Robert Fludd, like Kepler, is concerned with a Pythagorean and Platonic theme; but while Fludd's discussion is primarily concerned with the number mysticism of the Greek philosophers, Kepler arrives at an exact explanation of the structure of the cosmos in terms of a divine harmony based on geometry and music
