Just for the sake of illustration, in order to show the "universal relationship" between the numbers 6, 7 and 8
(the six basic colors of the color wheel in accord with white, the seven notes of the music scale, and hence
"one octave"), if you take six coins of equal diameter, say six pennys, and laid them on the table in the form
a hexagram, where each penny touched the edge of the next penny, you could then place a seventh penny in the
center and all pennys will still touch ... a pattern by the way (i.e., honeycomb effect), that retains its form
and can be repeated unto infinity, merely by adding more pennys to "the outside." Hence illustrating the universality
between a hexagram and the numbers 6 and 7.

And guess what? It also seems to incorporate the six days of Creation, as well as the seventh, where God rests
on the Sabbath (within the center of the first six). Hmm ... And of course there's the obvious relation to the
six basic colors and the color white. But how does this effect the musical scale you say? Well, if you were to
circumscribe a circle around the original pattern of seven (including the penny in the middle), you have the eighth
configuration or eighth note, and hence "one octave." And thus becomes the "embodiment" of the original seven.
Hmm ... Now what is the deal about "circumcision" occurring on the "eighth day?"

Finally, if you take the "eighth note," which is also the same note as the first, except at higher level, as well
as the embodiment of the seven notes as a whole (i.e., the greater circle), you can then generate a "new level" of
notes and, by circumsbribing it (with an even greater circle), it becomes the next octave up ... all of which gives
rise to the notion of "harmonics" ...

So can anybody see a pattern here?
