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]

  • What exactly are harmonics and how do they appear?
    Sinusoidal waves don't have harmonics because it's exactly sine waves which combined can construct other waveforms The fundamental wave is a sine, so you don't need to add anything to make it the sinusoidal signal About the oscilloscope Many signals have a large number of harmonics, some, like a square wave, in theory infinite
  • theory - Does the difference in harmonic series between instruments . . .
    The easiest to understand are harmonics, which was originally a mathematical term associated with a harmonic series, in which each term has a whole number ratio to all other terms Overtones rather are associated with a physical system and the term describes the different ways a vibrating system vibrates
  • WHY do harmonics happen? - Music: Practice Theory Stack Exchange
    Harmonics are present on a guitar string primarily because they are excited already when you pluck the string When you pluck the string you deflect it in a triangular shape, and Fourier transform of this shape defines the harmonic content
  • How do harmonics work? - Music: Practice Theory Stack Exchange
    The harmonics that are n * k * f0 (for all k in natural numbers, and f0 the frequency of the open string) are the ones that are not muted For example if the least number of divisions for your finger placement is 3, the unmuted harmonics are (3 * f0), (6 * f0), (9 * f0), and so on
  • Sources of Harmonics(Odd and Even) - Electrical Engineering Stack Exchange
    The question of "sources of harmonics" is sort of a chicken and egg question You can generate a waveform by combining harmonics, or you can generate harmonics by producing a waveform Usually, the second meaning is what is used The harmonics are generated by whatever process created the waveform
  • Filter design according to harmonics in an inverter
    And so on for other frequencies of interest Probably, getting Fsw itself down to some 100s or 10s of mV is the primary goal, and harmonics fall trivially after that, but some frequencies bands may end up peaked due to component parasitics and layout, and this can necessitate revisions, including adding a high-frequency filter
  • harmonics - What is the correct relationship between active, reactive . . .
    These values match and I have showed them in the output of my copied script below There is no active power by higher harmonics, since the voltage does not have higher harmonics And the same is true for reactive power of both fundamental and higher harmonics: this is zero for the fundamental harmonic since the voltage and current are in-line
  • What are the actual notes of each natural harmonic?
    5th fret harmonics are the same note as the open string, 7th fret harmonics are the same as the 7th fret notes (low to high - b,e,a,d,f#,b) Touch and tapped harmonics are the same as the fretted note assuming you are touching, tapping one octave higher and pinch harmonics change depending on where you pick pinch the note
