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.

Robert Schumann was a German composer and influential music critic. He is widely regarded as one of the greatest composers of the Romantic era. Schumann left the study of law, intending to pursue a career as a virtuoso pianist. He had been assured by his teacher Friedrich Wieck that he could become the finest pianist in Europe, but a hand injury ended this dream. Schumann then focused his musical energies on composing.
Schumann's published compositions were written exclusively for the piano until 1840; he later composed works for piano and orchestra; many Lieder (songs for voice and piano); four symphonies; an opera; and other orchestral, choral, and chamber works. Works such as Carnaval, Symphonic Studies, Kinderszenen, Kreisleriana, and the Fantasie in C are among his most famous. His writings about music appeared mostly in the Neue Zeitschrift für Musik (New Journal for Music), a Leipzig-based publication which he jointly founded.
In 1840, Schumann married Friedrich Wieck's daughter Clara, against the wishes of her father, following a long and acrimonious legal battle, which found in favour of Clara and Robert. Clara also composed music and had a considerable concert career as a pianist, the earnings from which, before her marriage, formed a substantial part of her father's fortune.
Schumann suffered from a mental disorder, first manifesting itself in 1833 as a severe melancholic depressive episode, which recurred several times alternating with phases of ‘exaltation’ and increasingly also delusional ideas of being poisoned or threatened with metallic items. After a suicide attempt in 1854, Schumann was admitted to a mental asylum, at his own request, in Endenich near Bonn. Diagnosed with "psychotic melancholia", Schumann died two years later in 1856 without having recovered from his mental illness.

Dmitri Shostakovich was a Russian pianist and composer of the Soviet period. He is regarded as one of the major composers of the 20th century.
Shostakovich achieved fame in the Soviet Union under the patronage of Soviet chief of staff Mikhail Tukhachevsky, but later had a complex and difficult relationship with the government. Nevertheless, he received accolades and state awards and served in the Supreme Soviet of the RSFSR (1947–1962) and the Supreme Soviet of the Soviet Union (from 1962 until his death).
A polystylist, Shostakovich developed a hybrid voice, combining a variety of different musical techniques into his works. His music is characterized by sharp contrasts, elements of the grotesque, and ambivalent tonality; the composer was also heavily influenced by the neo-classical style pioneered by Igor Stravinsky, and (especially in his symphonies) by the late Romanticism associated with Gustav Mahler.
Shostakovich's orchestral works include 15 symphonies and six concerti. His chamber output includes 15 string quartets, a piano quintet, two piano trios, and two pieces for string octet. His solo piano works include two sonatas, an early set of preludes, and a later set of 24 preludes and fugues. Other works include three operas, several song cycles, ballets, and a substantial quantity of film music; especially well known is The Second Waltz, Op. 99, music to the film The First Echelon (1955–1956), as well as the suites of music composed for The Gadfly.
