question:
Passage: Wood was born in Oxford Street, London, the only child of Henry Joseph Wood and his wife Martha, née Morris. Wood senior had started in his family's pawnbroking business, but by the time of his son's birth he was trading as a jeweller, optician and engineering modeller, much sought-after for his model engines. It was a musical household: Wood senior was an amateur cellist and sang as principal tenor in the choir of St Sepulchre-without-Newgate, known as "the musicians' church".   His wife played the piano and sang songs from her native Wales. They encouraged their son's interest in music, buying him a Broadwood piano, on which his mother gave him lessons. The young Wood also learned to play the violin and viola.
Wood received little religious inspiration at St Sepulchre, but was deeply stirred by the playing of the resident organist, George Cooper, who allowed him into the organ loft and gave him his first lessons on the instrument. Cooper died when Wood was seven, and the boy took further lessons from Cooper's successor, Edwin M. Lott, for whom Wood had much less regard. At the age of ten, through the influence of one of his uncles, Wood made his first paid appearance as an organist at St Mary Aldermanbury, being paid half a crown.  In June 1883, visiting the Fisheries Exhibition at South Kensington with his father, Wood was invited to play the organ in one of the galleries, making a good enough impression to be engaged to give recitals at the exhibition building over the next three months. At this time in his life, painting was nearly as strong an interest as music, and he studied in his spare time at the Slade School of Fine Art. He remained a life-long amateur painter.After taking private lessons from the musicologist Ebenezer Prout, Wood entered the Royal Academy of Music at the age of seventeen, studying harmony and composition with Prout, organ with Charles Steggall, and piano with Walter Macfarren. It is not clear whether he was a member of Manuel Garcia's singing class, but it is certain that he became its accompanist and was greatly influenced by Garcia. Wood also accompanied the opera class, taught by Garcia's son Gustave. Wood's ambition at the time was to become a teacher of singing, and he gave singing lessons throughout his life. He attended the classes of as many singing teachers as he could, although by his own account, "I possess a terrible voice. Garcia said it would go through a brick wall. In fact, a real conductor's voice.". 
Question: What is the last name of the person whose mother gave him piano lessons?
answer:
Wood.


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: Opeth recorded its debut album, Orchid, with producer Dan Swanö in April 1994. Because of distribution problems with the newly formed Candlelight Records, the album was not released until May 15, 1995, and only in Europe. Orchid tested the boundaries of traditional death metal, featuring acoustic guitars, piano, and clean vocals.After a few live shows in the United Kingdom, Opeth returned to the studio in March 1996 to begin work on a second album, again produced by Dan Swanö. The album was named Morningrise, and was released in Europe on June 24, 1996. With only five songs, but lasting 66 minutes, it features Opeth's longest song, the twenty-minute "Black Rose Immortal". Opeth toured the UK in support of Morningrise, followed by a 26-date Scandinavian tour with Cradle of Filth. While on tour, Opeth attracted the attention of Century Media Records, who signed the band and released the first two albums in the United States in 1997.In 1997, after the tour, Åkerfeldt and Lindgren dismissed De Farfalla for personal reasons, without the consent of Nordin. When Åkerfeldt informed Nordin, who was on a vacation in Brazil, Nordin left the band and remained in Brazil for personal reasons. Former Eternal members, drummer Martín López (formerly of Amon Amarth) and bassist Martín Méndez, responded to an ad at a music shop placed by Åkerfeldt. López and Méndez were fans of the band and took the ads down themselves so no other musicians could apply for the job. Åkerfeldt and Lindgren did not want the Martíns to join at first, due to them already knowing each other; they felt that they wanted two strangers so that there wouldn't be two camps in the band, but eventually hired both. López made his debut with Opeth playing on a cover version of Iron Maiden's "Remember Tomorrow", which was included on the album A Call to Irons: A Tribute to Iron Maiden.With a larger recording budget from Century Media, Opeth began work on its third album, with noted Swedish producer Fredrik Nordström, at Studio Fredman in August 1997. Although Opeth had Méndez, due to time constraints Åkerfeldt played bass on the album. My Arms, Your Hearse was released to critical acclaim on August 18, 1998. 
Question: What was the name of the person that played bass guitar on  My Arms, Your Hearse?
answer:

Åkerfeldt.
