One of the leading English composers of his generation, Vaughan Williams was a pupil of Parry, Charles Wood and Stanford, and later of Bruch and Ravel. In his work as a composer he went some way towards creating a specifically English musical idiom, influenced by his interest in folk-song, but colored by his own personal vision and language. Vaughan Williams wrote nine symphonies, the first of these A Sea Symphony, with words taken from Walt Whitman, the second "A London" Symphony and the third a "Pastoral" Symphony. The Sixth Symphony, completed in it's first version in 1947, seemed to break new ground and was followed by a seventh, the Sinfonia Antartica. Compositions by Vaughan Williams for solo instrument and orchestra include the pastoral romance The Lark Ascending, for solo violin, and a Concerto accademico for solo violin and string orchestra. There is an attractive concerto for oboe and two more unusual concertos, one for harmonica and the other for bass tuba. Flos campi uses a solo viola and is scored also for a small choir and chamber orchestra. He made direct use of folk-song in his three Norfolk Rhapsodies, his Fantasia on Greensleeves, for solo flute, harp and strings and in his English Folksong Suite for military band, among other works. His Fantasia on a Theme by Thomas Tallis for two string orchestras returns to the 16th century for it's musical inspiration.
