The global electromagnetic resonance phenomenon is named after physicist Winfried Otto Schumann who predicted it mathematically in 1952. Schumann resonances are the principal background in the part of the electromagnetic spectrum [2] from 3 Hz through 60 Hz [3] and appear as distinct peaks at extremely low frequencies around 7.83 Hz (fundamental), 14.3, 20.8, 27.3, and 33.8 Hz.
Robert Schumann. This list of compositions by Robert Schumann is classified into piano, vocal, orchestral and chamber works. All works are also listed separately, by opus number. Schumann wrote almost exclusively for the piano until 1840, when he burst into song composition around the time of his marriage to Clara Wieck. The list is based on ...
Winfried Otto Schumann (May 20, 1888 – September 22, 1974) was a German physicist and electrical engineer who predicted the Schumann resonances, a series of low-frequency resonances caused by lightning discharges in the atmosphere.
Schumann's writing for piano and string quartet – two violins, one viola and one cello – was in contrast with earlier piano quintets with different combinations of instruments, such as Schubert's Trout Quintet (1819). Schumann's ensemble became the template for later composers including Brahms, Franck, Fauré, Dvořák and Elgar. [126]
The fundamental Schumann resonance is at approximately 7.83 Hz, the frequency at which the wavelength equals the circumference of the Earth, and higher harmonics occur at 14.1, 20.3, 26.4, and 32.4 Hz, etc. Lightning strikes excite these resonances, causing the Earth–ionosphere cavity to "ring" like a bell, resulting in a peak in the noise ...
In 1861, five years after Schumann's death, his father-in-law Friedrich Wieck published a third edition under the editorial pseudonym "DAS" (an acronym for Der alte Schulmeister). This edition attempted to reconcile the differences between the earlier two, and bore both the previous titles XII Études Symphoniques and Études en forme de ...
This list is based upon the Thematisch-Bibliographisches Werkverzeichnis, a comprehensive catalogue of Schumann's works compiled by Margit L. McCorkle and published in 2003. Since Schumann's death scholars have made several separate attempts to catalogue his works not published with opus numbers.
