Problem: Given the question: Given the below context:  "Erschallet, ihr Lieder" (literally: sound, you songs) is a festive concerto, marked Coro by Bach. Words and music are possibly based on an earlier lost secular Glückwunschkantate (congratulatory cantata). A printing of Franck's works contains a cantata for New Year's Day, Erschallet nun wieder, glückwünschende Lieder (Sound again, congratulating songs) that may have served as a model. The movement is in da capo form: the first section is repeated after a contrasting middle section. It is scored for three "choirs": one of trumpets, another of strings and bassoon, and a four-part chorus. The number three, symbolizing the Trinity, appears again in the 3/8 time signature and in the use of three trumpets. The first part opens with trumpet fanfares, alternating with flowing coloraturas in the strings. The voices enter as a third homophonic choir. They repeat the first measure of the fanfare motif on the word "Erschallet" (resound!), as the trumpets echo the motif. The voices repeat the motif from the second measure of the fanfare on "ihr Lieder", and the trumpets echo it again. The chorus repeats measures 3 and 4 on "erklinget, ihr Saiten", commanding the strings to play. As a culmination, the first syllable of "seligste Zeiten" (most blessed times) is held on a seventh chord (first in measure 53), during which the instruments play their motifs.In the middle section in A minor the trumpets rest while the other instruments play colla parte with the voices. Polyphonic imitation expands on the idea that God will prepare the souls to be his temples. The first sequence progresses from the lowest to the highest voice, with entrances after two or three measures. The highest voice begins the second sequence, and the other voices enter in closer succession, one or two measures apart. Gardiner interprets the polyphony as "conjuring before us the elegant tracery of those 'temples' which God promises to make of our souls". The first part is repeated as da capo.The movement is comparable to the opening of Tönet, ihr Pauken!...  Guess a valid title for it!

The answer is:
Erschallet, ihr Lieder, erklinget, ihr Saiten!, BWV 172


input question: Given the below context:  Throughout the 360° Tour, the band worked on multiple album projects, including: a traditional rock album produced by Danger Mouse; a dance record produced by RedOne and will.i.am; and Songs of Ascent. However, the latter was not completed to their satisfaction, and by December 2011, Clayton admitted it would not come to fruition. The sessions with Danger Mouse instead formed the foundation of U2's next album, and they worked with him until May 2013 before enlisting the help of producers Paul Epworth, Ryan Tedder, Declan Gaffney, and Flood. The band suspended work on the album late in 2013 to contribute a new song, "Ordinary Love", to the film Mandela: Long Walk to Freedom. The track, written in honour of Nelson Mandela, won the 2014 Golden Globe Award for Best Original Song. In November 2013, U2's long-time manager Paul McGuinness stepped down from his post as part of a deal with Live Nation to acquire his management firm, Principle Management. McGuinness, who had managed the group for over 30 years, was succeeded by Guy Oseary. In February 2014, another new U2 song, the single "Invisible", debuted in a Super Bowl television advertisement and was made available in the iTunes Store at no cost to launch a partnership with Product Red and Bank of America to fight AIDS. Bono called the track a "sneak preview" of their pending record.On 9 September 2014, U2 announced their thirteenth studio album, Songs of Innocence, at an Apple product launch event, and released it digitally the same day to all iTunes Store customers at no cost. The release made the album available to over 500 million iTunes customers in what Apple CEO Tim Cook called "the largest album release of all time." Apple reportedly paid Universal Music Group and U2 a lump sum for a five-week exclusivity period in which to distribute the album and spent US$100 million on a promotional campaign. Songs of Innocence recalls the group members' youth in Ireland, touching on childhood experiences, loves and losses, while paying tribute to their musical...  Guess a valid title for it!???

Please answer this: Given the below context:  The year 1960 marked another turning point in Shostakovich's life: he joined the Communist Party. The government wanted to appoint him General Secretary of the Composers' Union, but in order to hold that position he was required to attain Party membership. It was understood that Nikita Khrushchev, the First Secretary of the Communist Party from 1953 to 1964, was looking for support from the leading ranks of the intelligentsia in an effort to create a better relationship with the Soviet Union's artists. This event has been interpreted variously as a show of commitment, a mark of cowardice, the result of political pressure, or his free decision. On the one hand, the apparat was undoubtedly less repressive than it had been before Stalin's death. On the other, his son recalled that the event reduced Shostakovich to tears, and he later told his wife Irina that he had been blackmailed. Lev Lebedinsky has said that the composer was suicidal. From 1962, he served as a delegate in the Supreme Soviet of the USSR. Once he joined the Party, several articles he did not write denouncing individualism in music were published in Pravda under his name. In joining the party, Shostakovich was also committing himself to finally writing the homage to Lenin that he had promised before. His Twelfth Symphony, which portrays the Bolshevik Revolution and was completed in 1961, was dedicated to Vladimir Lenin and called "The Year 1917." Around this time, his health began to deteriorate. Shostakovich's musical response to these personal crises was the Eighth String Quartet, composed in only three days. He subtitled the piece "To the victims of fascism and war", ostensibly in memory of the Dresden fire bombing that took place in 1945. Yet, like the Tenth Symphony, this quartet incorporates quotations from several of his past works and his musical monogram. Shostakovich confessed to his friend Isaak Glikman, "I started thinking that if some day I die, nobody is likely to write a work in memory of me, so I had better write one myself."...
