There are six harmonic means that can be placed between 1 and 1/2 when dividing a string. Put another way, there are six, and only six, precise locations to physically-derive through the nature of plucking a string harmonic sounds.
The two primary divisions of an Octave are the Parents Heaven and Earth. and the six children of the trigrams are the six harmonic ratios found in music.
The Complete binary opposites of the Trigrams Ch'ien (father; Creative) and K'un (mother; Receptive) are binary opposites of light and dark and are in the order:
1/1 the fundamental | 1/2 the octave |
 |  |
3/2 the perfect fifth | 4/3 the perfect fourth |
 |  |
5/4 the Major Third | 6/5 the minor third |
 |  |
5/3 the Major Sixth | 8/5 the minor sixth |
