Neolithic Number Eight Permeates the Great Pyramid of Egypt. Also the modern piano keyboard. Here’s how.

- First use of eight (8). The featured picture illustrates an octahedron. It is a symmetrical, eight-faced, triangulated figure. All angles at their corners are 60°. Bisect the featured picture across the square at the center. The bisected octahedron then becomes two square based pyramids. The above I call the positive. The below I call the negative. All square base pyramids imply an attached equal and opposite pyramid. The mere existence of any square base pyramid, implies a counterpart. Granted, the Great Pyramid of Egypt has differing angles. It uses isosceles triangles. But, the extra four reverse-faced pyramid is still implied. When they are joined, the square bases become internal. They literally disappear. There no longer is a separated square base. We have our first usage eight. As, 4 faces (postive) + 4 (negative) faces = 8.

### 2nd Usage of Neolithic Number Eight

- Each side of the square base measures 440 shorter Egyptian cubits. Shorter cubits are 1.718…feet. A more encompassing measure is the Great Cubit. It measures 55 shorter Egyptian cubits. Thus each side of the Great Pyramid of Egypt is 8 Great Cubits. 440⁄ 8 = 55. Reference John Michell,
*The View Over Atlantis*. Therefore the Great Pyramid is 8 x 8 Great Cubits.

### Neolithic Number Eight and Musical Octaves on the Piano Keyboard

- Last, but not least. We will tie the Great Pyramid into concert note A-440
*and its octaves*. Its essential measures come from octaves of the concert note A 440. A higher octave doubles the vibrations per second. The lower octave cuts them in half. The lowest note on the 88-keyed piano is “A”. It vibrates 27.5 times per second. On the Steinway below, it is the furthest note to the left.
