Leopold Koželuch.
Born 26 June 1747 in the town of Velvary, in Bohemia (present-day Czech Republic).
Died 7 May 1818
He moved to Prague to further his musical education, before moving in Vienna in 1778, where he was based for the remainder of his career. In Vienna he achieved renown as a composer, pianist and teacher, and from 1792 until his death in 1818 he held royal appointments as Kammer Kapellmeister (music director) and Hofmusik Compositor (composer), as Wolfgang Amadeus Mozart’s successor.
This is a classical era piece; the composer was already 9 years old when Mozart was born.
Koželuch's compositional output included sonatas and concertos for keyboard, the instrument in which he specialised, as well as chamber music, choral music and opera.
By 1790, a time at which Mozart and Joseph Haydn were at the height of their careers, Koželuch's reputation was such as to move Ernst Ludwig Gerber to say the following of his status within Europe: "Leopold Kozeluch is without question with young and old the generally most loved among our living composers, and this with justification". Koželuch left around 400 compositions. Among these there are about thirty symphonies, twenty-two piano concertos, including a concerto for piano four-hands, arguably one of the best examples of this rare genre, two clarinet concertos, twenty-four violin sonatas, sixty-three piano trios, six string quartets, two oratorios (one of which, Moisè in Egitto, has recently been produced and recorded), nine cantatas and various liturgical works.
