Benjamin Britten is one most important British composers from the second half of the twentieth century. Remarkably, he focused on opera, a dying genre, at least in its current form. Britten's contributions however, among which Peter Grimes, The Rape of Lucretia, Gloriana, The Turn of the Screw, and Death in Venice, managed to remain core repertoire for opera companies to this day. Many of these productions included a role for his artistic partner and life companion Peter Pears. Britten also wrote a number of lieder for this tenor, among which his Serenade for tenor, horn and string orchestra. Yet, Britten excelled in many more genres. He wasn't even 20 years old when he composed his brilliant Phantasy for hobo quartet and his friendship with the legendary cellist Rostropovich led to a Cello sonata, three Suites for cello solo and a Symphony for Cello and orchestra in the 1960s.

Britten never became Master of the Queen's Music, yet he surely had feeling for public sentiments. For example, as a pacifist, he taught his people about world peace through his War Requiem from 1962. Britten was an excellent interpreter of his own work, just like Bartók and Stravinsky. Many of his recordings have been matched, but never exceeded.

Ralph Vaughan Williams was an English composer and folk song collector. His works include operas, ballets, chamber music, secular and religious vocal pieces and orchestral compositions including nine symphonies, written over nearly fifty years. Strongly influenced by Tudor music and English folk-song, his output marked a decisive break in British music from its German-dominated style of the 19th century.
He wrote many works for amateur and student performance. He was musically a late developer, not finding his true voice until his late thirties; his studies in 1907–08 with the French composer Maurice Ravel helped him clarify the textures of his music.
Vaughan Williams is among the best-known British symphonists, noted for his very wide range of moods, from stormy and impassioned to tranquil, from mysterious to exuberant. Among the most familiar of his other concert works are Fantasia on a Theme by Thomas Tallis (1910) and The Lark Ascending (1914). His vocal works include hymns, folk-song arrangements and large-scale choral pieces. He wrote eight works for stage performance between 1919 and 1951. Although none of his operas became popular repertoire pieces, his ballet Job: A Masque for Dancing (1930) was successful and has been frequently staged.

Finzi took private lessons with Farrar from 1914-1916 and then with Bairstow from 1917-1922. He mainly underwent influences by Elgar and Vaughan Williams, loved the life in the country and developed his own, intimate style. He concentrated on songs and song cycles such as Oh fair to see, Till earth outwears, and A young man’s exhortation, preferably on texts by Hardy. Amongst his other works are a clarinet concerto from 1949 and Dies natalis for high voice and string orchestra (1939).
