"I believe sound to be a real substance of unknown and wonderful tenuity, emanating as absolute corpuscles interatomic particles from matter when induced by percussion. Sound has a velocity of 20,000 feet per second in vacuo, in air, 1120 ft. per second. The substance thus disseminated is an actual component of the agitated mass and were this condition to continue indefinitely the mass would eventually be disintegrated. I think the true definition of sound is "a certain order of etheric flow, consisting of actual radiant atomic corpuscles ruptured from a static condition by disturbance of atomic equilibrium."

"Every gaseous molecule is a resonator sensitive to any and all discordant sounds. Inaudibility is no proof of nonexistence of acoustic force. The ear could not hear the total acoustic force transmitted by 1,000,000,000,000 molecules."

"The molecule contains only harmony, discordance in any mass is only the result of differentiated chords. Any mass so differentiated can be brought into harmony or equated, by the proper chords, be that mass animal matter, vegetable matter or mineral, solid, liquid or gas. Discordance cannot exist in the molecule as a unit. That which we term discord exists in sound itself, not in matter."

"If our hearing were intensified a billion times, we might be able to hear the chord note of aggregate masses, the fundamental monotones of liquids, and gas volumes, the musical notes given off by electric streams and hear the streams of light as they come through a window, as plainly as we now hear the wind in the trees."

"There is still a vast region of the inaudible to be conquered, but the audible has been so conquered in my instruments as to put me in touch with the inaudible. It is now only necessary to ascertain the terrestrial chord masses, and when I have conquered the inaudible I shall be able to control this most subtle force and run sympathetic machinery."

He tested inaudible vibration by means of the magnetic needle and alteration of light frequencies to produce sound colors.

Pythagoras believed and taught that the laws of harmony control the movements of the heavenly bodies. Is it not proof of the wonderful outreach of the mind of this ancient philosopher that it has taken nineteen centuries to even indicate that this is a fact, and not merely a "poetic fancy?"
