Definitions for "Overtone"
One of the harmonics faintly heard with and at a higher frequency than a fundamental tone as it dies away, produced by some aliquot portion of the vibrating sting or column of air which yields the fundamental tone; one of the natural harmonic scale of tones, as the octave, twelfth, fifteenth, etc.; an aliquot or "partial" tone; a harmonic. See Harmonic, and Tone.
Similar in concept to a harmonic. Overtones are tones produced by an instrument (or sound source) that are higher in frequency than the fundamental. They may or may not coincide with the frequencies of a harmonic series (harmonics), but they usually do. The difference is that harmonics are always musically related to the fundamental in that they are integer multiples of it. Overtones of a sound are often exactly the same as its harmonics except the first overtone is considered the second harmonic because the first harmonic is the fundamental. Overtones are also sometimes called partials (more on them later).
An odd numbered multiple of the fundamental frequency.
a sun-damaged undertone
The mass color, self color or top color as exhibited by reflected light in contrast to the undertone that may show through the main color.

(aka overblow, toot, hoot) - the trumpet-like note produced by tighter lip tension and characteristic of B-type accompaniments
(usually plural) an ulterior implicit meaning or quality; "overtones of despair"
A line in a vibrational spectrum arising from a formally forbidden transition. They arise because anharmonicity in the potential curve of a vibrating bond can relax the selection rules for vibrational transitions.
