<human>: Sullivan was born in London on 13 May 1842. His father was a military bandmaster, and by the time Arthur had reached the age of eight, he was proficient with all the instruments in the band. In school he began to compose anthems and songs. In 1856, he received the first Mendelssohn Scholarship and studied at the Royal Academy of Music and then at Leipzig, where he also took up conducting. His graduation piece, completed in 1861, was a suite of incidental music to Shakespeare's The Tempest. Revised and expanded, it was performed at the Crystal Palace in 1862 and was an immediate sensation. He began building a reputation as England's most promising young composer, composing a symphony, a concerto, and several overtures, among them the Overture di Ballo, in 1870.  His early major works for the voice included The Masque at Kenilworth (1864); an oratorio, The Prodigal Son (1869); and a dramatic cantata, On Shore and Sea (1871). He composed a ballet, L'Ile Enchantee (1864) and incidental music for a number of Shakespeare plays. Other early pieces that were praised were his Symphony in E, Concerto for Cello and Orchestra, and Overture in C (In Memoriam) (all three of which premiered in 1866). These commissions, however, were not sufficient to keep Sullivan afloat. He worked as a church organist and composed numerous hymns, popular songs, and parlour ballads.  Sullivan's first foray into comic opera was Cox and Box (1866), written with librettist F. C. Burnand for an informal gathering of friends. Public performance followed, with W. S. Gilbert (then writing dramatic criticism for the magazine Fun) saying that Sullivan's score "is, in many places, of too high a class for the grotesquely absurd plot to which it is wedded." Nonetheless, it proved highly successful, and is still regularly performed today. Sullivan and Burnand's second opera, The Contrabandista (1867) was not as successful. CANNOTANSWER
