[electrical power] Harmonic voltages and currents in an electric power system are a result of non-linear electric loads. Harmonic frequencies in the power grid are a frequent cause of power quality problems. Harmonics in power systems result in increased heating in the equipment and conductors, misfiring in variable speed drives, and torque...

• (n.) Secondary and less distinct tones which accompany any principal, and apparently simple, tone, as the octave, the twelfth, the fifteenth, and the seventeenth. The name is also applied to the artificial tones produced by a string or column of air, when the impulse given to it suffices only to make a part of the string or column vibrate; o...

Vibrations at frequencies which are integer multiples of that of a fundamental vibration: the ascending notes C, G, E, C', E', G' comprise a fundamental with its first five higher harmonics. Apart from their musical consonance, they are important because any periodically repeated signal – a vo...

A frequency that is a whole-number multiple of the fundamental frequency. For example, if the fundamental frequency of a sound is 440Hz, then the first two harmonics are 880Hz and 1,320Hz (1.32kHz). See Overtone

Chime-like sounds achieved in two ways: 1) natural harmonics - by touching a string at any equidistant division of the string length (typically 5th, 7th, and 12th fret), directly above the fret with left hand, and striking hard with the right-hand fingers or pick near the bridge where there is more string resistance; or 2) artificial harmonics - to...

Harmonics are overtones of the string and produce soft flutelike sounds when the string is lightly touched at specific fractional divisions (nodal points). Natural harmonics are produced on open strings, and artificial or stopped harmonics are produced on stopped strings.

harmonics 1. The science of musical sounds. 2. The partials or overtones of a fundamental tone. 3. Integral multiples of the fundamental frequency. The first harmonic is the fundamental, and the second is twice the frequency of the fundamental, etc. Also called overtones, these are vibrations at frequencies that are multiples of the fundamentals....

In music, a series (the `harmonic series`) of partial vibrations that combine to form a musical tone. When a stretched string or a column of air in a tube is made to vibrate, it does so as a whole, in two halves, three thirds, four quarters, etc., all at the same time. The easiest vibration to hear is that of the whole. It is the lowest n...
