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 physics, acoustics, and telecommunications, a harmonic is a sinusoidal wave with a frequency that is a positive integer multiple of the fundamental frequency of a periodic signal The fundamental frequency is also called the 1st harmonic; the other harmonics are known as higher harmonics
  • Fundamental Frequency And Harmonics: What Are They?
    Harmonics are defined as an unwanted higher frequency component that is an integer multiple of the fundamental frequency Harmonics create a distortion in the fundamental waveform
  • 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”
  • Physics Tutorial: Fundamental Frequency and Harmonics
    When the guitar is played, the string, sound box and surrounding air vibrate at a set of frequencies to produce a wave with a mixture of harmonics The exact composition of that mixture determines the timbre or quality of sound that is heard
  • What Is a Harmonic? Sound, Physics, and Math Explained
    A harmonic is a vibration whose frequency is a whole-number multiple of a base frequency, called the fundamental If a guitar string vibrates at a fundamental frequency of 100 Hz, its harmonics occur at 200 Hz (2nd harmonic), 300 Hz (3rd harmonic), 400 Hz (4th harmonic), and so on
  • 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
  • What are Harmonics and how does it affect an Electrical System?
    Discover what harmonics are and how they affect electrical systems Learn about the causes of harmonic distortion, its impact on power quality, and how to mitigate its effects to ensure efficient and stable operation of electrical equipment
  • 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
  • What are harmonics? - The Ethan Hein Blog
    This is a problem, because harmonics are important, not just for music theory, but also for audio engineering, as well as many non-music-related subfields in physics
  • What is a harmonic in physics? - California Learning Resource Network
    In physics, a harmonic refers to a component frequency of a signal that is an integer multiple of the fundamental frequency Understanding harmonics is crucial in diverse fields, from signal processing and telecommunications to acoustics, optics, and even power electronics
