overtone
noun (Concise Encyclopedia)In acoustics, a faint higher tone contained within almost any musical tone. A body producing a musical pitchsuch as a taut string or a column of air within the tubular body of a wind instrumentvibrates not only as a unit but simultaneously also in sections, resulting in the presence of a series of overtones within the fundamental tone (i.e., the one identified as the actual pitch). Harmonics are a series of overtones resulting when the partial vibrations are of equal sections (e.g., halves, thirds, fourths). Partials are nonharmonic overtonesthat is, tones the frequencies of which lie outside the harmonic series. Overtones contribute greatly to the timbre of a given sound source, even though few listeners are aware of hearing any pitch except the fundamental. There are a few rare examples of the human voice creating overtones, notably in the chants of the Tibetan monks and the songs of the Tuvan throat singers. The latter can sometimes produce two overtones.
