Definitions for "Harmonics"
The doctrine or science of musical sounds.
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.
Another term for overtones. Tones of a higher pitch that are present in every musical sound though are not sung or played.
higher and quieter sounds mixed together (not heard separately)
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 - touching a string with the index finger of the right hand twelve frets higher than any fretted note and plucking the string with either the thumb or third finger of the right hand.
the vibration of an air column or string is divided into fractions (for example, two halves, three thirds, etc) which sound simultaneously to produce sound
