Since all of music is based on the fundamental cycles of the original SPIN momentum or "abstract motion" of absolute SPACE, the primal or TRUE Alpha Chord (the first triad) is the combination of the vibrations of the initial fractally involved triune fields of the first Logos (the primal Monad) of cosmogenesis... That ultimately resolves, holographically, on the lowest order (fourth world) physical plane, into the seven fold (octaval) fields of consciousness -- whose frequencies are analogous to the sounds of the diatonic (seven note) musical scale. Pythagorus called the *sound* of this (*bubbles within bubbles* or "wheels within wheels") structure of fundamental space that produced the first Chords, "The music of the spheres".
By combining different groups of analogous primal field frequencies, their harmonics, and their ratios, we can see many other musical scales developing in different cultures throughout history. http://en.wikipedia.org/wiki/Musical_scale
The basis of all this can be easily confirmed by studying the following diagrams... Keeping in mind the three fundamental principles and the analogy and correspondence between all coadunate but not consubstantial fields of consciousness -- due to the fundamental fractal field involution and *holographic* nature of the primal Cosmos whose "center is everywhere and circumference nowhere"... Thus, the analogous zero-point energy (ZPE) fields in the apparently *empty* sub quantum space between the so called "particles" that generate and energize them... And, the *chakra* fields within and surrounding the physical body that links it with our seven states of altered consciousness.
