question:
Passage: Bach's early cantatas are Choralkonzerte (chorale concertos) in the style of the 17th century, different from the recitative and aria cantata format associated with Neumeister that Bach started to use for church cantatas in 1714. Wolff points out the relation of Bach's early cantatas to works by Dieterich Buxtehude, with whom Bach had studied in Lübeck. Christ lag in Todes Banden shows similarities to a composition of Johann Pachelbel based on the same Easter chorale. Although there is no evidence that Bach and Pachelbel met, Bach grew up in Thuringia while Pachelbel was based in the same region, and Bach's elder brother and teacher Johann Christoph Bach studied with Pachelbel in Erfurt. Another of Pachelbel's works appears to be referenced in the early Bach cantata, Nach dir, Herr, verlanget mich, BWV 150, and there has been recent speculation that Bach wanted to pay tribute to Pachelbel after his death in 1706.The texts for the early cantatas were drawn mostly from biblical passages and hymns. Features characteristic of his later cantatas, such as recitatives and arias on contemporary poetry, were not yet present, although Bach may have heard them in oratorios by Buxtehude, or even earlier. Instead, these early cantatas include 17th-century elements such as motets and chorale concertos. They often begin with an instrumental sinfonia or sonata (sonatina). The following table lists the seven extant works composed by Bach until 1708, when he moved on to the Weimar court.
Bach uses the limited types of instruments at his disposal for unusual combinations, such as two recorders and two viole da gamba in the funeral cantata Gottes Zeit ist die allerbeste Zeit, also known as Actus Tragicus. He uses instruments of the continuo group as independent parts, such as a cello in Nach dir, Herr, verlanget mich and a bassoon in Der Herr denket an uns. The cantata for the inauguration of a town council is richly scored for trumpets, woodwinds and strings. Wolff notes:
The overall degree of mastery by which these early pieces compare favourably with the best church compositions from the first decade of the eighteenth century ... proves that the young Bach did not confine himself to playing organ and clavier, but, animated by his Buxtehude visit, devoted considerable time and effort to vocal composition. The very few such early works that exist, each a masterpiece in its own right, must constitute a remnant only ... of a larger body of similar compositions.
The Bach scholar Richard D. P. Jones notes in The Creative Development of Johann Sebastian Bach:
"His remarkable flair for text illustration is evident even in the early cantatas, particularly the two finest of them, the Actus tragicus, BWV 106, and Christ lag in Todes Banden, BWV 4. We already sense a powerful mind behind the notes in the motivic unity of the early cantatas, in the use of reprise to bind their mosaic forms together ...". 
Question: What often begin with an instrumental sinfonia or sonata?
answer:
cantatas.


question:
Passage: Caspar David Friedrich was born on 5 September 1774, in Greifswald, Swedish Pomerania, on the Baltic coast of Germany. The sixth of ten children, he was brought up in the strict Lutheran creed of his father Adolf Gottlieb Friedrich, a candle-maker and soap boiler. Records of the family's financial circumstances are contradictory; while some sources indicate the children were privately tutored, others record that they were raised in relative poverty. Caspar David was familiar with death from an early age. His mother, Sophie Dorothea Bechly, died in 1781 when he was just seven. A year later, his sister Elisabeth died, while a second sister, Maria, succumbed to typhus in 1791. Arguably the greatest tragedy of his childhood happened in 1787 when his brother Johann Christoffer died: at the age of thirteen, Caspar David witnessed his younger brother fall through the ice of a frozen lake, and drown. Some accounts suggest that Johann Christoffer perished while trying to rescue Caspar David, who was also in danger on the ice.
Friedrich began his formal study of art in 1790 as a private student of artist Johann Gottfried Quistorp at the University of Greifswald in his home city, at which the art department is now named Caspar-David-Friedrich-Institut in his honour. Quistorp took his students on outdoor drawing excursions; as a result, Friedrich was encouraged to sketch from life at an early age. Through Quistorp, Friedrich met and was subsequently influenced by the theologian Ludwig Gotthard Kosegarten, who taught that nature was a revelation of God. Quistorp introduced Friedrich to the work of the German 17th-century artist Adam Elsheimer, whose works often included religious subjects dominated by landscape, and nocturnal subjects. During this period he also studied literature and aesthetics with Swedish professor Thomas Thorild. Four years later Friedrich entered the prestigious Academy of Copenhagen, where he began his education by making copies of casts from antique sculptures before proceeding to drawing from life. Living in Copenhagen afforded the young painter access to the Royal Picture Gallery's collection of 17th-century Dutch landscape painting. At the Academy he studied under teachers such as Christian August Lorentzen and the landscape painter Jens Juel. These artists were inspired by the Sturm und Drang movement and represented a midpoint between the dramatic intensity and expressive manner of the budding Romantic aesthetic and the waning neo-classical ideal. Mood was paramount, and influence was drawn from such sources as the Icelandic legend of Edda, the poems of Ossian and Norse mythology. 
Question: What is the full name of the man who taught taught that nature was a revelation of God to the person who lost his mother when he was seven?
answer:
Ludwig Gotthard Kosegarten.


question:
Passage: Critical reception to Vol. 3: The Subliminal Verses was generally positive. It received a score of 70% on review aggregator Metacritic based on 12 reviews. Johnny Loftus of AllMusic called the album "not just another flashy alt-metal billboard", praising the band's "dedication to making it a Slipknot album". Todd Burns of Stylus wrote that people who accuse the band of having "softened" are "mistaking softness for maturation". Burns went on to call the album "the best pop inflected metal album since System of a Down's Toxicity". Sean Richardson of Entertainment Weekly gave the album an A− and wrote that it is a "deranged hippie update" of Slayer's "masterpiece" Reign in Blood, which was also produced by Rubin. Q hailed Vol. 3: The Subliminal Verses as "a triumph". John Robb of PlayLouder complimented Slipknot's unexpected rise to become "one of the biggest groups in the world", dubbing "Before I Forget" a "classic [Slipknot] anthem". Robb added that the album is better than Iowa, citing its "differing textures". Rolling Stone gave the album a rating of 3 out of 5, stating the album presented "newer extremes" for the band, "which in Slipknot's case means tunefulness and traditional song structures".A review from the BBC praised the album, declaring that there "is no finer metal band on the planet". It cited the group's integration of "hyperactive bass drums, complex, compelling riffs and ridiculously fast fretwork" with more melodic styles and described Vermilion as "the key track ... an emotional, melodramatic, utterly convincing rollercoaster ride".Alternative Press criticized the album, writing that it "plays out like a tepid, second-rate version of Iowa, which pretty much makes it a third-rate anything else." Yahoo!'s Chris Heath also reviewed the album negatively, writing that "The Nameless" combines "the ludicrously vicious and ridiculously placid" and that by doing so makes the track feel "awkward". Heath added, "the themes are predictably absurd ... yet mildly comical given the inclusion of such disparate styles stationed side by side."Vol. 3: The Subliminal Verses peaked at position number two on the US Billboard 200, online, Australian Recording Industry Association, and Canadian sales charts. The album was certified Platinum in the United States on February 21, 2005. In 2006, the band won their first Grammy for Best Metal Performance with "Before I Forget". In 2009, Metal Hammer called it one of the "Albums of the Decade". It was also rated 31st in UK magazine Kerrang!'s "The 50 Best Albums of the 21st Century" reader poll.
In 2005, the album was ranked number 396 in Rock Hard magazine's book of The 500 Greatest Rock & Metal Albums of All Time.
