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.
For works published by Schumann or prepared by him for publication and published posthumously, opus numbers are given. For works not published or prepared for publication by Schumann, McCorkle's RSW (" Robert-Schumann-Werkverzeichnis ") numbers are listed first, and Hofmann-Keil (H/K) WoO (" Werke ohne Opuszahl ") numbers, which are still ...
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.
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 ...

A typical performance lasts approximately 18–19 minutes. In the months leading up to working on this symphony Schumann had been studying and transcribing the music of Beethoven, whose influence can be heard in the first two movements, particularly the use of short motives rather than full-blown melodies in the first movement and the solemn rhythms of the second, which are reminiscent of the ...
The main movement of the concerto is marked Allegro affettuoso; its origin lay in the one-movement fantasy written by Schumann in 1841, at whose core is the musical development of the conflict between the boisterous Florestan and the dreamy Eusebius, two characters Schumann often used to express the duality of being. The movement is set in 4/4 ...
