All vibrating aggregates possess some degree of concordance (sympathy) in relation to other aggregates. This because all tones/vibrations/oscillations spontaneously create a series of overtones, sub-tones and harmonics in general. The degree, strength and type of attraction is determined by the number of concordant frequencies. (See Part 01).
