IN: Robert Schumann (; 8 June 1810 - 29 July 1856) was a German composer and an influential music critic. He is widely regarded as one of the greatest composers of the Romantic era. Schumann left the study of law, intending to pursue a career as a virtuoso pianist. He had been assured by his teacher Friedrich Wieck, a German pianist, that he could become the finest pianist in Europe, but a hand injury ended this dream.

Schumann was born in Zwickau, in the Kingdom of Saxony, the fifth and last child of Johanna Christiane (nee Schnabel) and August Schumann. Schumann began to compose before the age of seven, but his boyhood was spent in the cultivation of literature as much as music - undoubtedly influenced by his father, a bookseller, publisher, and novelist.  Schumann began receiving general musical and piano instruction at the age of seven from Johann Gottfried Kuntzsch, a teacher at the Zwickau high school. The boy immediately developed a love of music and worked at creating musical compositions himself, without the aid of Kuntzsch. Even though he often disregarded the principles of musical composition, he created works regarded as admirable for his age. The Universal Journal of Music 1850 supplement included a biographical sketch of Schumann that noted, "It has been related that Schumann, as a child, possessed rare taste and talent for portraying feelings and characteristic traits in melody, - ay, he could sketch the different dispositions of his intimate friends by certain figures and passages on the piano so exactly and comically that everyone burst into loud laughter at the similitude of the portrait."  At age 14, Schumann wrote an essay on the aesthetics of music and also contributed to a volume, edited by his father, titled Portraits of Famous Men. While still at school in Zwickau, he read the works of the German poet-philosophers Schiller and Goethe, as well as Byron and the Greek tragedians. His most powerful and permanent literary inspiration was Jean Paul, a German writer whose influence is seen in Schumann's youthful novels Juniusabende, completed in 1826, and Selene.  Schumann's interest in music was sparked by seeing a performance of Ignaz Moscheles playing at Karlsbad, and he later developed an interest in the works of Beethoven, Schubert and Mendelssohn. His father, who had encouraged the boy's musical aspirations, died in 1826 when Schumann was 16. Neither his mother nor his guardian thereafter encouraged a career in music. In 1828 Schumann left school, and after a tour during which he met Heinrich Heine in Munich, he went to Leipzig to study law (to meet the terms of his inheritance). In 1829 his law studies continued in Heidelberg, where he became a lifelong member of Corps Saxo-Borussia Heidelberg.

Answer the question at the end by quoting:

Tangerine Dream is a German electronic music band founded in 1967 by Edgar Froese. The group has seen many personnel changes over the years, with Froese being the only continuous member until his death in January 2015. The best known line-up of the group was its mid-70s trio of Froese, Christopher Franke, and Peter Baumann. In the late 1970s, Johannes Schmoelling replaced Baumann.
Edgar Froese arrived in West Berlin in the mid-1960s to study art. His first band, the psychedelic rock-styled The Ones, disbanded after releasing only one single. After The Ones, Froese experimented with musical ideas, playing smaller gigs with a variety of musicians. Most of these performances were in the famous Zodiak Free Arts Lab, although one grouping also had the distinction of being invited to play for the surrealist painter Salvador Dali. The music was partnered with literature, painting, early forms of multimedia, and more. It seemed as though only the most outlandish ideas attracted any attention, leading Froese to comment, "In the absurd often lies what is artistically possible." As members of the group came and went, the direction of the music continued to be inspired by the Surrealists, and the group came to be called by the surreal-sounding name of Tangerine Dream, inspired by the line "tangerine trees and marmalade skies" from The Beatles' track "Lucy in the Sky with Diamonds."  Froese was fascinated by technology and skilled in using it to create music. He built custom-made instruments and, wherever he went, collected sounds with tape recorders for use in constructing musical works later. His early work with tape loops and other repeating sounds was the obvious precursor to the emerging technology of the sequencer, which Tangerine Dream quickly adopted upon its arrival.  The first Tangerine Dream album, Electronic Meditation, was a tape-collage Krautrock piece, using the technology of the time rather than the synthesized music they later became famous for. The line-up for the album was Froese, Klaus Schulze, and Conrad Schnitzler. Electronic Meditation was published by Ohr in 1970, and began the period known as the Pink Years (the Ohr logo was a pink ear). But starting with their second album, Alpha Centauri, the group has been a trio or occasionally duo of electronic instruments, commonly augmented by guitar from Froese (or, much later, other musicians as well), and occasionally also other instruments. Of these, drums from Christopher Franke and organ from Steve Schroyder (on Alpha Centauri) or Peter Baumann (on subsequent releases) feature prominently in the band's music during the early 70s. They also started their heavy usage of the Mellotron during this period.

input: Octagonal drum is a type of Manchu folk art that was very popular among bannermen, especially in Beijing. It is said that octagonal drum originated with the snare drum of the Eight-banner military and the melody was made by the banner soldiers who were on the way back home from victory in the battle of Jinchuan. The drum is composed of wood surrounded by bells. The drumhead is made by wyrmhide with tassels at the bottom. The colors of the tassels are yellow, white, red, and blue, which represent the four colors of the Eight Banners. When artists perform, they use their fingers to hit the drumhead and shake the drum to ring the bells. Traditionally, octagonal drum is performed by three people. One is the harpist; one is the clown who is responsible for harlequinade; and the third is the singer.  "Zidishu" is the main libretto of octagonal drum and can be traced back to a type of traditional folk music called the "Manchu Rhythm". Although Zidishu was not created by Han Chinese, it still contains many themes from Chinese stories, such as Romance of the Three Kingdoms, Dream of the Red Chamber, Romance of the West Chamber, Legend of the White Snake and Strange Stories from a Chinese Studio. Additionally, there are many works that depict the lives of Bannermen. Aisin Gioro Yigeng, who was pen named "Helu" and wrote the sigh of old imperial bodyguard, as the representative author. Zidishu involves two acts of singing, which are called dongcheng and xicheng.  After the fall of the Qing dynasty, the influence of the octagonal drum gradually reduced. However, the Chinese monochord and crosstalk which derived from octagonal are still popular in Chinese society and the new generations. Many famous Chinese monochord performers and crosstalkers were the artists of octagonal drum, such as De Shoushan and Zhang Sanlu.
