Piano four hands in the context of Duet (music)

A duet (Italian: duo or duetto) is a musical composition for two performers in which the performers have equal importance to the piece, often a composition involving two singers or two pianists. It differs from a harmony, as the performers take turns performing a solo section rather than performing simultaneously. A piece performed by two pianists performing together on the same piano is a "piano duet" or "piano four hands". A piece for two pianists performing together on separate pianos is a "piano duo".

"Duet" is also used as a verb for the act of performing a musical duet, or colloquially as a noun to refer to the performers of a duet.

Franz Peter Schubert (/ˈʃuːbərt/; German: [fʁants ˈpeːtɐ ˈʃuːbɐt]; 31 January 1797 – 19 November 1828) was an Austrian composer of the late Classical and early Romantic eras. Despite his short life, Schubert left behind a vast oeuvre, including more than 600 Lieder (art songs in German) and other vocal works, seven complete symphonies, sacred music, operas, incidental music, and a large body of piano and chamber music. His major works include "Erlkönig", "Gretchen am Spinnrade", and "Ave Maria"; the Trout Quintet; the Symphony No. 8 in B minor (Unfinished); the Symphony No. 9 in C major (The Great); the String Quartet No. 14 in D minor (Death and the Maiden); the String Quintet in C major; the Impromptus for solo piano; the last three piano sonatas; the Fantasia in F minor for piano four hands; the opera Fierrabras; the incidental music to the play Rosamunde; Schwanengesang; and the song cycles Die schöne Müllerin and Winterreise.

Born in the Himmelpfortgrund suburb of Vienna, Schubert showed uncommon gifts for music from an early age. His father gave him his first violin lessons and his elder brother gave him piano lessons, but Schubert soon exceeded their abilities. In 1808, at the age of eleven, he became a pupil at the Stadtkonvikt school, where he became acquainted with the orchestral music of Joseph Haydn, Wolfgang Amadeus Mozart, and Ludwig van Beethoven. He left the Stadtkonvikt at the end of 1813 and returned home to live with his father, where he began studying to become a schoolteacher. Despite this, he continued his studies in composition with Antonio Salieri and still composed prolifically. In 1821, Schubert was admitted to the Gesellschaft der Musikfreunde as a performing member, which helped establish his name among the Viennese citizenry. He gave a concert of his works to critical acclaim in March 1828, the only time he did so in his career. He died eight months later at the age of 31, the cause officially attributed to typhoid fever, but believed by some historians to be syphilis.

According to the Grove Dictionary of Music and Musicians, there are two kinds of piano duet: "[pieces of music] for two players at one instrument, and those in which each of the two pianists has an instrument to themselves." In American English usage, the former is often referred to as a "piece for four hands", or "piano four hands". Grove notes that the one-piano duet has a larger repertory, but has come to be regarded as a modest, domestic form of music-making by comparison with "the more glamorous two-piano duet". The two-piano form is also referred to as a piano duo, although this term also refers to a set of two piano players who play together regularly (thus, duos play duets).

The piano duet came to popularity in the second half of the 18th century.

The Fantasia in F minor by Franz Schubert, D.940 (Op. posth. 103), for piano four hands (two players at one piano), is one of Schubert's most important works for more than one pianist and one of his most important piano works altogether. He composed it in 1828, the last year of his life. A dedication to his former pupil Caroline Esterházy can only be found in the posthumous first edition, not in Schubert's autograph.

Musicologist Christopher Gibbs has described the work as "among not only his greatest but his most original" compositions for piano duet.
