The Planet-4D Model: An Original Hypersymmetric Music Space Based on Graph Theory

International audienceBeside a geometrical part that has been calculated with the help of the graph theory, the Planet-4D model includes twelve ideograms that can either symbolize notes, chords or scales depending on the context. Based on symmetry principles, it presents the following innovations: the hyper spherical environment grants each symbol an equivalent physical position, and involves more symmetries than any 3D model, the concept of bi-dimensional ideograms provides an intuitive understanding of pitch relationships, it contains implicitly the chromatic and fourth circles as well as the original Tonnetz.NB: the pertinence of this model is effective when demonstrated in motion with colored CGI animations of the 4D Space including sound examples.
