Input: Consider Input: Passage: Colour lies at the heart of Messiaen's music. He believed that terms such as "tonal", "modal" and "serial" are misleading analytical conveniences. For him there were no modal, tonal or serial compositions, only music with or without colour. He said that Claudio Monteverdi, Mozart, Chopin, Richard Wagner, Mussorgsky and Stravinsky all wrote strongly coloured music.In some of Messiaen's scores, he notated the colours in the music (notably in Couleurs de la cité céleste and Des canyons aux étoiles...)—the purpose being to aid the conductor in interpretation rather than to specify which colours the listener should experience. The importance of colour is linked to Messiaen's synaesthesia, which he said caused him to experience colours when he heard or imagined music (he said that he did not perceive the colours visually). In his multi-volume music theory treatise Traité de rythme, de couleur, et d'ornithologie ("Treatise of Rhythm, Colour and Birdsong"), Messiaen wrote descriptions of the colours of certain chords. His descriptions range from the simple ("gold and brown") to the highly detailed ("blue-violet rocks, speckled with little grey cubes, cobalt blue, deep Prussian blue, highlighted by a bit of violet-purple, gold, red, ruby, and stars of mauve, black and white. Blue-violet is dominant").When asked what Messiaen's main influence had been on composers, George Benjamin said, "I think the sheer ... colour has been so influential, ... rather than being a decorative element, [Messiaen showed that colour] could be a structural, a fundamental element, ... the fundamental material of the music itself.". 
Question: What is the name of the person who said Monteverdi, Mozart, Chopin, Wagner, Mussorgsky, and Stravinsky all wrote strongly coloured music?

Output: Messiaen.


Input: Consider Input: 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?

Output: Wood.


Input: Consider Input: Passage: County Cork, Ireland, 1920. Dr. Damien O'Donovan is about to leave his native village to practise medicine in a London hospital. Meanwhile, his brother Teddy commands the local flying column of the Irish Republican Army. After a hurling match, Damien witnesses the summary execution of his friend, Micheál Ó Súilleabháin, by British Black and Tans. Although shaken, Damien rebuffs his friends' entreaties to stay in Ireland and join the IRA, saying that the war is unwinnable. As he is leaving town, Damien witnesses the British Army vainly trying to intimidate a railway personnel for refusing to permit the troops to board. In response, Damien decides to stay and is sworn into Teddy's IRA brigade.
After drilling in the mountains, the column raids the village's Royal Irish Constabulary barracks to acquire revolvers, then uses them to assassinate four Auxiliaries. In the aftermath, Anglo-Irish landowner Sir John Hamilton coerces one of his servants, IRA member Chris Reilly, into passing information to the British Army's Intelligence Corps. As a result, the entire brigade is arrested. In their cell, Damien meets the train driver, Dan, a union official who shares Damien's socialist views.
Meanwhile, British officers interrogate Teddy, pulling out his fingernails when he refuses to give them the names of IRA members. Johnny Gogan, a British soldier of Irish descent, helps the prisoners escape, but three are left behind. After the actions of Sir John and Chris are revealed to the IRA's intelligence network, both are taken hostage. As Teddy is still recovering, Damien is temporarily placed in command. News arrives that the three remaining IRA prisoners have been tortured and shot. Simultaneously, the brigade receives orders to "execute the spies". 
Question: Which organization does Sir John Hamilton's servant betray?


Output: IRA.
