There is only one wave shape, the sine wave. Waves are just built upon it.

If you want to read an excellent e-book on sacred geometry and how it relates to the world, the Hebrew language, our bodies, and much more than I can summarize here, check out Alphabet of the Heart.

The shapes below show the different platonic solids and how they harmonically fit inside a circle.

The five Platonic Solids are the only perfect three-dimensional objects. In each solid, the lines are all the same length, the faces are all the same, and the angles are all the same. Each solid fits together inside a sphere perfectly.

We are currently in the third density, the yellow octahedron. We have already started the transformation into the fourth density, the green star tetrahedron.

The table shown below shows each density and its corresponding shape, color, name, number and tone. Geometry is frozen music in this sea of endless light.

Shape	Name	Number	Tone
	Circle	One	Do
	Icosahedron	Two	Re
	Octahedron	Three	Mi
	Star Tetrahedron	Four	Fa
	Cube	Five	So
	Dodecahedron	Six	La
	Icosahedron	Seven	Ti
	Circle	Eight	Do
