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.
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 ...
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 ...

Bunte Blätter (English: Colorful Leaves), Op. 99, is a collection of piano pieces by Robert Schumann assembled from earlier unpublished pieces after the success of the Album for the Young (Album für die Jugend), Op. 68. Upon publication the pieces were issued both as a complete set and individual pieces, the latter in differently colored covers.
