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.

In the summer, the Schumanns returned to Leipzig for the actual premiere of Genoveva. The opera was received poorly, and received only three performances. Disappointed, Schumann returned to Dresden in July.
Liederkreis, Op. 39, is a song cycle composed by Robert Schumann. Its poetry is taken from Joseph von Eichendorff's collection entitled Intermezzo. Schumann wrote two cycles of this name – the other being his Opus 24, to texts by Heinrich Heine – so this work is also known as the Eichendorff Liederkreis. Schumann wrote, "The voice alone ...
