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.

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 ...
Kreisleriana is a very dramatic work and is viewed by some critics as one of Schumann's finest compositions. [3] [4] [5] In 1839, soon after publishing it, Schumann called it in a letter "my favourite work," remarking that "The title conveys nothing to any but Germans.
Undertone series on C. [1] In music, the undertone series or subharmonic series is a sequence of notes that results from inverting the intervals of the overtone series.While overtones naturally occur with the physical production of music on instruments, undertones must be produced in unusual ways.
Schumann in a Josef Kriehuber etching from 1839, the year preceding his marriage to Clara. It was at this time that he began to compose vocal music prolifically. The following is a list of the complete vocal output of Robert Schumann (8 June 1810 – 29 July 1856). Schumann was one of the most prolific composers of the nineteenth century.
