1867, in literal sense, from over + tone (n.); a loan-translation of German Oberton, first used by German physicist Hermann Ludwig Ferdinand von Helmholtz (1821-1894) as a contraction of Overpartialto [..]

Describes the color glint of a gemstone or Pearl in various lighting.

n. A harmonic.

Of a sinusoidal wave, an integral multiple of the frequency, i.e., the fundamental, of the wave, other than the fundamental itself. Note 1: The first overtone is twice the frequency of the fundamental, and thus corresponds to the second harmonic; the second overtone is three times the frequency of the fundamental, and thus corresponds to the third [..]

(n) (usually plural) an ulterior implicit meaning or quality(n) a harmonic with a frequency that is a multiple of the fundamental frequency

The secondary colour of the surface of a natural or cultured pearl, created when the layers of nacre split white light into its component colours

[0] any frequency

1. Any simple sine tone (not necessarily harmonic) which exists above a fundamental frequency and which fuses with other components to form a single complex tone; any partial that occurs above the perceived pitch of a complex tone. Contrast with undertone. 2. The term overtone has frequently been used interchangeably with harmonic -- meaning a simp [..]

A multiple of the fundamental frequency. The first overtone is double the fundamental, the second is three times the fundamental.

 

Any frequency higher than the fundamental frequency of a sound. The fundamental frequency and the overtones together are called partials. Harmonics are partials whose frequencies are whole number mult [..]
