A series of overtones that are harmonics of the fundamental pitch.

A series of overtones that are harmonics (ratios with common divisor or multiples of the divisor) with/of the fundamental pitch.

**Law of Harmonic Pitch**

"Any aggregate in a state of vibration develops in addition to its fundamental pitch a series of vibration in symmetrical sub-multiple portions of itself, bearing ratios of one, two, three or more times its fundamental pitch." [Keely, pre 1894]

**Law of Harmonic Vibrations**

"All coherent aggregates are perpetually vibrating at a period-frequency corresponding to some harmonic ratio of the fundamental pitch of the vibrating body; this pitch is a multiple of the pitch of the atomole." [Keely, pre1894]
