input: Please answer the following: Given the following context:  The opening soprano solo in E major, "I know that my Redeemer liveth" is one of the few numbers in the oratorio that has remained unrevised from its original form. Its simple unison violin accompaniment and its consoling rhythms apparently brought tears to Burney's eyes. It is followed by a quiet chorus that leads to the bass's declamation in D major: "Behold, I tell you a mystery", then the long aria "The trumpet shall sound", marked pomposo ma non-allegro ("dignified but not fast"). Handel originally wrote this in da capo form, but shortened it to dal segno, probably before the first performance. The extended, characteristic trumpet tune that precedes and accompanies the voice is the only significant instrumental solo in the entire oratorio. Handel's awkward, repeated stressing of the fourth syllable of "incorruptible" may have been the source of the 18th-century poet William Shenstone's comment that he "could observe some parts in Messiah wherein Handel's judgements failed him; where the music was not equal, or was even opposite, to what the words required". After a brief solo recitative, the alto is joined by the tenor for the only duet in Handel's final version of the music, "O death, where is thy sting?"  The melody is adapted from Handel's 1722 cantata Se tu non-lasci amore, and is in Luckett's view the most successful of the Italian borrowings. The duet runs straight into the chorus "But thanks be to God".The reflective soprano solo "If God be for us" (originally written for alto) quotes Luther's chorale Aus tiefer Not. It ushers in the D major choral finale: "Worthy is the Lamb", leading to the apocalyptic "Amen" in which, says Hogwood, "the entry of the trumpets marks the final storming of heaven". Handel's first biographer, John Mainwaring, wrote in 1760 that this conclusion revealed the composer "rising still higher" than in "that vast effort of genius, the Hallelujah chorus". Young writes that the "Amen"  should, in the manner of Palestrina, "be delivered as though through the aisles and...  answer the following question:  What is the name of the person that wrote I know that my Redeemer liveth?

Please answer this: Given the following context:  The term "Viking metal" has sometimes been used as a nickname for the 1990s Norwegian black metal scene, which was "noisy, chaotic, and often augmented by sorrowful keyboard melodies". It has also been variously described as a subgenre of black metal, albeit one that abandoned black metal's Satanic imagery, "slow black metal" with influences from Nordic folk music, straddling black metal and folk metal almost equally, or running the gamut from "folk to black to death metal". Typically, Viking metal artists rely extensively on keyboards, which are often played at a "swift, galloping pace". These artists often add "local cultural flourishes" such as traditional instruments and ethnic melodies. It is similar to folk metal, and is sometimes categorized as such, but it uses folk instruments less extensively. For vocals, Viking metal incorporates both singing and the typical black metal screams and growls. Overall, Viking metal is hard to define since, apart from certain elements like anthem-like choruses, it is not based entirely on musical features and overlaps with other metal genres, with origins in black and death metal Some bands, such as Unleashed and Amon Amarth, play death metal, but incorporate Viking themes and thus are labeled as part of the genre. Generally, Viking metal is defined more by its thematic material and imagery than musical qualities. Rather than being a mock-up of medieval music, "it is in the band names, album titles, artwork of album covers and, especially, in the song lyrics that Viking themes are so evident." Viking metal, and the closely related style pagan metal, is more of a term or "etiquette" than a musical style. Since they are defined chiefly by lyrical focus, any musical categorizations of these two styles is controversial. Thus, Viking metal is more of a cross-genre term than a descriptor of a certain sound. Ashby and Schofield write that "The term 'Viking metal' is one of many that falls within a complex web of genres and subgenres, the precise form of which is constantly...  answer the following question:  What genres are defined chiefly by lyrical focus?

input question: Given the following context:  Morrison and EMI producer Norman Smith negotiated Pink Floyd's first recording contract, and as part of the deal, the band agreed to record their first album at EMI Studios in London. Mason recalled that the sessions were trouble-free. Smith disagreed, stating that Barrett was unresponsive to his suggestions and constructive criticism. EMI-Columbia released The Piper at the Gates of Dawn in August 1967. The album peaked at number 6, spending 14 weeks on the UK charts. One month later, it was released under the Tower Records label. Pink Floyd continued to draw large crowds at the UFO Club; however, Barrett's mental breakdown was by then causing serious concern. The group initially hoped that his erratic behaviour would be a passing phase, but some were less optimistic, including Jenner and his assistant, June Child, who commented: "I found [Barrett] in the dressing room and he was so ... gone. Roger Waters and I got him on his feet, [and] we got him out to the stage ... The band started to play and Syd just stood there. He had his guitar around his neck and his arms just hanging down".Forced to cancel Pink Floyd's appearance at the prestigious National Jazz and Blues Festival, as well as several other shows, King informed the music press that Barrett was suffering from nervous exhaustion. Waters arranged a meeting with psychiatrist R. D. Laing, and though Waters personally drove Barrett to the appointment, Barrett refused to come out of the car. A stay in Formentera with Sam Hutt, a doctor well established in the underground music scene, led to no visible improvement. The band followed a few concert dates in Europe during September with their first tour of the US in October. As the US tour went on, Barrett's condition grew steadily worse. During appearances on the Dick Clark and Pat Boone shows in November, Barrett confounded his hosts by not responding to questions and staring off into space. He refused to move his lips when it came time to mime "See Emily Play" on Boone's show. After these embarrassing...  answer the following question:  What was the name of the person that Pink Floyd hoped that their erratic behavior would be a passing phase????

Barrett
