Figure 1.7 shows graphically how a fundamental or base frequency multiplies through the creation of harmonics (overtones) and their interactions by summation and difference tones to create the multitude of frequencies perceptible as the energy filled active universe. Out of order of One (unison or singularity) comes chaos. This graphic shows also how harmonic series (as also music scales) are derived from a single fundamental or keynote. [See Part 9 for more detail.]
