harmonics
n 1: the study of musical sound

Harmonics \Har*mon"ics\ (-[i^]ks), n.
1. The doctrine or science of musical sounds.
[1913 Webster]

2. pl. (Mus.) 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; overtones.
[1913 Webster]

  • Harmonic - Wikipedia
    In music, harmonics are used on string instruments and wind instruments as a way of producing sound on the instrument, particularly to play higher notes and, with strings, obtain notes that have a unique sound quality or "tone colour" On strings, bowed harmonics have a "glassy", pure tone
  • Harmonics and Harmonic Distortion in an Electrical System
    What are Harmonics? Harmonics (or the distortion of waveforms) are voltages or currents that operate at a frequency which is an integer (whole-number) multiple of the fundamental frequency These multiples are added to the fundamental producing a waveform known as a “complex waveform”
  • Fundamental Frequency And Harmonics: What Are They?
    What Are Harmonics? Harmonics are sinusoidal components whose frequencies are integer multiples of a fundamental frequency In power-quality work, harmonic components combine with the fundamental to produce a non-sinusoidal voltage or current waveform
  • Harmonics (electrical power) - Wikipedia
    Harmonics are usually classified by two different criteria: the type of signal (voltage or current), and the order of the harmonic (even, odd, triplen, or non-triplen odd); in a three-phase system, they can be further classified according to their phase sequence (positive, negative, zero)
  • Harmonics. What are they? What do they do? - EEP
    To summarize: the harmonics are nothing less than the components of a distorted waveform and their use allows us to analyse any periodic nonsinusoidal waveform through different sinusoidal waveform components
  • Fundamental Frequency and Harmonics - The Physics Classroom
    These patterns are only created within the object or instrument at specific frequencies of vibration; these frequencies are known as harmonic frequencies, or merely harmonics At any frequency other than a harmonic frequency, the resulting disturbance of the medium is irregular and non-repeating
  • Harmonics - Eaton
    Harmonics are distorted electrical wave-forms that introduce inefficiencies into your electrical system, such as excess heat and local power company fees Harmonics are caused by common electrical devices and can be reduced significantly
  • Harmonics and Overtones: Definition, Formula Examples
    Harmonics are whole-number multiples of a fundamental frequency See how they differ from overtones, the string and pipe formulas, timbre and examples
  • Harmonics - an overview | ScienceDirect Topics
    Harmonics are known as distortions in the form of voltage and current, which are driven by the nonlinear loads in the network Harmonics can be basically asserted as the most common problem in renewable-based power generation technologies
  • HARMONIC Definition Meaning - Merriam-Webster
    The meaning of HARMONIC is musical
