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 human EEG studies, the term theta refers to frequency components in the 4–7 Hz range, regardless of their source. Cortical theta is observed frequently in young children. [14] In older children and adults, it tends to appear during meditative, drowsy, hypnotic or sleeping states, but not during the deepest stages of sleep. Theta from the ...
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 ...

In 1849, Robert Schumann explored the horn as a solo instrument, dedicating to it an "Adagio and Allegro," Op. 70, before embarking on the composition of an orchestral work featuring four solo horns (having also composed the "Five Songs based on Heinrich Laube's Hunting Compendium" for men's choir and four horns, Op. 137 that same year).
Album for the Young (Album für die Jugend), Op. 68, was composed by Robert Schumann in 1848 for his three daughters. The album consists of a collection of 43 short works. Unlike the Kinderszenen, they are suitable to be played by children or beginne
