The harmonic series (also overtone series) is the sequence of harmonics, musical tones, or pure tones whose frequency is an integer multiple of a fundamental frequency. Pitched musical instruments are often based on an acoustic resonator such as a string or a column of air, which oscillates at numerous modes simultaneously.
Because the overtone series rises infinitely from the fundamental with no periodicity, in Western music the equal temperament scale was designed to create synchronicity between different octaves. [ 2 ] [ 22 ] This was achieved by de-tuning certain intervals, such as the perfect fifth .
Using a high C rather than the high G of the overtone-series, the open-C tuning C-C-G-C-E-C. was used by Mick Ralphs for the songs "Can't Get Enough" and "Movin' On" on Bad Company's debut album. The lowest and second lowest C's differ by an octave; even when the lowest C-string is not struck, its sympathetic resonance improves the sound. [9]
A wave and its harmonics, with wavelengths ,,, …. The name of the harmonic series derives from the concept of overtones or harmonics in music: the wavelengths of the overtones of a vibrating string are ,,, etc., of the string's fundamental wavelength.
Overtone series, partials 1-5 numbered Play ⓘ.. Harry Partch, Ivor Darreg, and Ralph David Hill are among the many microtonalists to suggest that music has been slowly evolving to employ higher and higher harmonics in its constructs (see emancipation of the dissonance).
For instance: the frequency ratio 5:4 is equal to 4 ⁄ 5 of the string length and 4 ⁄ 5 is the complement of 1 ⁄ 5, the position of the fifth harmonic (and the fourth overtone). The Norwegian composer Eivind Groven also wrote a thesis on the scale of harmonics, claiming this to be the oldest usable scale, frequent in Norwegian folk music ...
In traditional music, the overtone scale persists in the music of peoples of South Siberia, especially in Tuvan music. Overtone singing and the sound of the Jew's harp are naturally rich in overtones, but melodies performed on the igil (bowed instrument distantly related to the violin) and plucked string instruments such as the doshpuluur or the chanzy also often follow the overtone scale ...
The C-C-G-C-E-G tuning uses the harmonic sequence (overtones) of the note C. When an open-note C-string is struck, its harmonic sequence begins with the notes (C,C,G,C,E,G,B♭,C). [3] [4] This overtone-series tuning was modified by Mick Ralphs, who used a high C rather than the high G for "Can't Get Enough" on Bad Company. Ralphs said, "It ...
