Sacred Geometry is what makes up our entire existence. Everything in our reality, all matter and elements come from the five platonic solids. These five platonic solids represent the shapes hexahedron, octahedron, tetrahedron, icosahedron, and the dodecahedron. The shapes that form the five Platonic Solids occur naturally and everywhere in nature. Each shape corresponds with a certain element or property of the universe. Earth (hexahedron), air (octahedron), fire (tetrahedron), water (icosahedron), and heaven (dodecahedron). These shapes are a very important part of understanding the world around us. In turn, Sacred Geometry is of vital importance.
Music uses the laws of vibration to manifest aurally what exists at the center of everything. Music uses the laws of physics and mathematics to bring out an emotional response in the listener. This emotional response is due to the way music speaks directly to the chakra centers and causes them to vibrate in harmony to the vibrations of the music moving through the air. Plato, who discovered the five Platonic solids, believed that music was the strongest of all life's influences. Plato's Republic describes the cosmos as being held together by eight spinning "whorls," like a giant spinning wheel with eight feminine weavers sounding the fabric of Creation. Each of the whorls contains a planet. On each planet is a siren that sings her particular note and emits her specific color; much like the chakras emitting a specific color.
Science is only now beginning to discover these interrelationships of sound and matter. Launching the new science of cymatics, Swiss researcher Hans Jenny conducted experiments showing that inert powders, pastes, and liquids, when animated by audible, pure tones, would form into flowing geometric patterns that mirrored those found throughout nature. He showed that there was a correlation between sound and form — that, in effect, the matter of the universe is a physical manifestation of vibration.
There have also been countless studies done on the geometric correspondence between human thoughts/emotions and the geometric shape that it causes. Studies have shown that water, when treated with love or beautiful music undergoes molecular change into beautiful, harmonious geometrical forms (when becoming a crystal formation). And the same happens in reverse: negative emotions or chaotic music cause the crystals of water to become disorganized and unlovely. Since we as humans are made up of over 70% water, it might be a good idea to pay attention to what type of music we are listening to as it directly affects our form and function.
