Ludwig van Beethoven was a German composer and pianist. A crucial figure in the transition between the Classical and Romantic eras in Western art music, he remains one of the most famous and influential of all composers. His best-known compositions include nine symphonies, five piano concertos, one violin concerto, 32 piano sonatas, 16 string quartets, his great Mass the Missa solemnis, and one opera, Fidelio. Together with Mozart and Haydn, he was part of the First Viennese School. Born in Bonn, then the capital of the Electorate of Cologne and part of the Holy Roman Empire, Beethoven displayed his musical talents at an early age and was taught by his father Johann van Beethoven and by composer and conductor Christian Gottlob Neefe. At the age of 21 he moved to Vienna, where he began studying composition with Joseph Haydn, and gained a reputation as a virtuoso pianist. He lived in Vienna until his death. By his late 20s his hearing began to deteriorate, and by the last decade of his life he was almost totally deaf. In 1811 he gave up conducting and performing in public but continued to compose; many of his most admired works come from these last 15 years of his life.

If you would open any biography of Franz Liszt, you would probably mostly read about his disquiet life as a piano virtuoso, his passionate love life, and the return to his catholic roots at the end of his life. Although all of this might be true, it only scratches the surface of his comprehensive musical personality. Liszt was a pianist, conductor, teacher and organiser, but above all he was a composer of a voluminous, capricious body of work. Even though his piano works formed his core business, he gave rise to the symphonic poem, got rid of the organ's stuffy appearance, and reinvigorated the oratorio. Moreover, with his piano transciptions of Bach's organ works and Berlioz's Symphonie Fantastique, he was an advocate of both old and new music.
Together with his son-in-law Richard Wagner, he was in the forefront of the Romantic movement and anticipated the musical revolutions of the early 20th century with his new composition techniques.

Franz Peter Schubert was an Austrian composer. Schubert already died before his 32nd birthday, but was extremely prolific during his lifetime. His output consists of over six hundred secular vocal works (mainly Lieder), seven complete symphonies, sacred music, operas, incidental music and a large body of chamber and piano music. Appreciation of his music while he was alive was limited to a relatively small circle of admirers in Vienna, but interest in his work increased significantly in the decades following his death. Felix Mendelssohn, Robert Schumann, Franz Liszt, Johannes Brahms and other 19th-century composers discovered and championed his works. Today, Schubert is ranked among the greatest composers of the late Classical and early Romantic eras and is one of the most frequently performed composers of the early nineteenth century.
It was in the genre of the Lied that Schubert made his most indelible mark. Prior to Schubert's influence, Lieder tended toward a strophic, syllabic treatment of text, evoking the folksong qualities engendered by the stirrings of Romantic nationalism. Schubert expanded the potentialities of the genre like no other composer before.

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.

Frédéric Chopin is one of the greatest composers of the Romantic piano tradition. He was a master in making the small form great. His ballades, mazurkas, polonaises, preludes, etudes and nocturnes all belong to the most popular standard works for piano ever written. As a child prodigy, Chopin grew up in a middle class family, who lived among the literati of Warsaw. When in 1830 the November Uprising broke out in Poland, the twenty year old Chopin stayed in Vienna. He became an exile and never returned to his mother country. He eventually settled in Paris. He avoided public concerts, but he did like performing in small settings, such as salons and at home for his friends. This way, Chopin built a reputation as an exceptional pianist, teacher and composer.
Chopin brought a unique synthesis between the Viennese bravado and the French/English lyric style. Even though his pieces often are technically very demanding, the focus was always on creating a lyric expression and poetic atmosphere. He invented the instrumental ballade, and brought salongenres to a higher level with his many innovations and refinements.

Sergei Vasilievich Rachmaninov was a Russian pianist, composer, and conductor of the late-Romantic period, some of whose works are among the most popular in the classical repertoire.
Born into a musical family, Rachmaninov took up the piano at age four. He graduated from the Moscow Conservatory in 1892 and had composed several piano and orchestral pieces by this time. In 1897, following the critical reaction to his Symphony No. 1, Rachmaninoff entered a four-year depression and composed little until successful therapy allowed him to complete his enthusiastically received Piano Concerto No. 2 in 1901. After the Russian Revolution, Rachmaninov and his family left Russia and resided in the United States, first in New York City. Demanding piano concert tour schedules caused his output as composer to slow tremendously; between 1918 and 1943, he completed just six compositions, including Rhapsody on a Theme of Paganini, Symphony No. 3, and Symphonic Dances. In 1942, Rachmaninov moved to Beverly Hills, California. One month before his death from advanced melanoma, Rachmaninov acquired American citizenship.
Early influences of Tchaikovsky, Rimsky-Korsakov, Balakirev, Mussorgsky, and other Russian composers gave way to a personal style notable for its song-like melodicism, expressiveness and his use of rich orchestral colors.[3] The piano is featured prominently in Rachmaninov's compositional output, and through his own skills as a performer he explored the expressive possibilities of the instrument.

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.
