Harmonics         
·noun The doctrine or science of musical sounds.
II. Harmonics ·noun 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.
Harmonic         
·adj ·Alt. of Harmonical.
II. Harmonic ·noun A musical note produced by a number of vibrations which is a multiple of the number producing some other; an overtone. ·see Harmonics.
harmonic         
a.; (also harmonical)
1.
Harmonious, concordant, consonant.
2.
Melodious, tuneful, musical.
3.
Pertaining to harmony, relating to music, musical.

Harmonic

A harmonic is a wave with a frequency that is a positive integer multiple of the fundamental frequency, the frequency of the original periodic signal, such as a sinusoidal wave. The original signal is also called the 1st harmonic, the other harmonics are known as higher harmonics. As all harmonics are periodic at the fundamental frequency, the sum of harmonics is also periodic at that frequency. The set of harmonics forms a harmonic series.

The term is employed in various disciplines, including music, physics, acoustics, electronic power transmission, radio technology, and other fields. For example, if the fundamental frequency is 50 Hz, a common AC power supply frequency, the frequencies of the first three higher harmonics are 100 Hz (2nd harmonic), 150 Hz (3rd harmonic), 200 Hz (4th harmonic) and any addition of waves with these frequencies is periodic at 50 Hz.

An nth characteristic mode, for n > 1, will have nodes that are not vibrating. For example, the 3rd characteristic mode will have nodes at 1 3 {\displaystyle {\tfrac {1}{3}}} L and 2 3 {\displaystyle {\tfrac {2}{3}}} L, where L is the length of the string. In fact, each nth characteristic mode, for n not a multiple of 3, will not have nodes at these points. These other characteristic modes will be vibrating at the positions 1 3 {\displaystyle {\tfrac {1}{3}}} L and 2 3 {\displaystyle {\tfrac {2}{3}}} L. If the player gently touches one of these positions, then these other characteristic modes will be suppressed. The tonal harmonics from these other characteristic modes will then also be suppressed. Consequently, the tonal harmonics from the nth characteristic modes, where n is a multiple of 3, will be made relatively more prominent.

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. On stringed instruments, harmonics are played by touching (but not fully pressing down the string) at an exact point on the string while sounding the string (plucking, bowing, etc.); this allows the harmonic to sound, a pitch which is always higher than the fundamental frequency of the string.

1. Bank of India had granted loan to Harmonics Fabrics Fashions Ltd which had defaulted in repayment of instalments.
2. The frequencies of these natural oscillatory activities are in some cases close to those used in GSM technology or their harmonics, and may possibly give rise to resonant or other disturbing effects.
3. However, the entry–level unit lacks a number of the higher–end MEX–BT5100‘s more advanced audio capabilities, such as its EQ3 parametric leveler, and its BBE MP signal processing, which restores some of the sound quality lost through the compression of digital audio files by reamplifying acoustic details or "harmonics" that were reduced in the compression process.
4. And it brought the harmonics of multiculturalism all the way home in nominating Peter Boyer‘s "Ellis Island: The Dream of America." A note at posting time: The Grammys for best classical album, best choral performance and best classical contemporary composition have gone to the Naxos recording of William Bolcom‘s "Songs of Innocence and of Experience." Those nods and an award to Tim Handley for classical producer of the year in recognition of his work on several Naxos recordings bring the label‘s total of wins to four, out of 15 nominations.
