Keely’s Dominant, Harmonic and Enharmonic - These three interval designations appear to be correct as they are part of a system of energy and coincide with known musical terminalogy. The Dominant or 4++ position is a place of extreme polarization and power. The Harmonic/syntropic (3+, 2+, 1+) and Enharmonic/entropic (3-, 2-, 1-) are opposites with less the power of 4++. This number pair sequence is a gradient of power accumulation and dispersion and makes sense when considered as an associative triplet state as according to what Keely says: "All the dominant conditions of nature represent the focal centers towards which like surrounding ones become sympathetically subservient." [pg 179 of Keely and His Discoveries]

"Magnetism is of the atomic order? and not molecular? then it is not electrical in nature; so what then is the influence in an electromagnetic? The Dominant current of the electrical stream." [Keely and His Discoveries]

"The Dominant (of the Electrical Stream) creates or governs Magnetism on the Atomic Order of Vibration (High Vibratory)." [Keely and His Discoveries]

"Keely classes the cohesive force of molecular masses as the dominant order of the electric stream, the molecule owing its negative attractive quality to the magnetic element." [Keely and His Discoveries] This is what we today call valence.

"The Dominant current of the electrical stream is the electricity luminous." [Keely and His Discoveries]

"The fundamental mode of vibration changes as we reach the fifth subdivision etheric, to the dominant, the diatonic third of the mass chord, which controls the vibratory states of both etheron and interetheron." [Keely and His Discoveries]

"The magnetic cannot lead the electric, nor the electric the gravital, nor the gravital the magnetic. All are subservient to the dominant, as a train of cars is subservient to the locomotive which pulls it along; the only difference between the two is that one is sympathetic, the other mechanical. Though this is a crude illustration, it conveys a great truth in sympathetic philosophy. All sympathetic flows have this triune condition associated with them, the same as the molecular, atomic and etheric aggregations of all forms of visible matter; the compound etheric, or dominant, being the leader and yet one of the constituents of the molecule itself. The dominant we may call the etheric portion of the molecule; the harmonic, the atomic; and the enharmonic, the molecule itself. The dominant parts of the triune combination of the sympathetic streams are the leaders, toward which all co-ordinate to make up the sympathetic terrestrial envelope of the earth; the cerebral being the high dominant, or compound etheric, the luminiferous proper." [Keely and His Discoveries]

As we have associated the etheric with things Spiritual we see in Keely's above statement support to the adage that "spirit leads materialism".
