The Geometry of Music explores the space that music occupies. Early hints at this concept include the Flower of Life and other forms of platonic solids and Sacred Geometry. This isn’t the first time the Sacred Geometry has been used. The original use of shapes-as-sounds in formal music was found at the Rosslyn Chapel in Scotland. Music was decoded from carvings which represented the form of the wave observed when sand was placed on a skin. In more modern times, TOOL has written about Sacred Geometry in their newsletter, but as with anything else mystical and esoteric, TOOL may just be tooling around.
