Franz Lizst, born on 22 October 1811 died on 31 July 1886, was a Hungarian composer. A prolific composer, Liszt was one of the representatives of the New German School (German: Neudeutsche Schule). He left behind an extensive and diverse body of work. Among Liszt's musical contributions were the symphonic poem, developing thematic transformation as part of his experiments in musical form, and radical innovations in harmony. The largest and best-known portion of Liszt's music is his original piano work. During the Weimar period, he composed 19 Hungarian Rhapsodies, themselves revisions of his own Magyar Dalok/Rhapsódiák. Liszt's piano works are usually divided into two categories: original works, and transcriptions, paraphrases, or fantasies on works by other composers. Examples of his own works are Harmonies poétiques et religieuses of May 1833 and the Piano Sonata in B minor (1853). Liszt's transcriptions of other composers include Schubert songs, fantasies on operatic melodies, and his piano arrangements of symphonies by Hector Berlioz and Ludwig van Beethoven. Liszt also made piano arrangements of his own instrumental and vocal works, such as the arrangement of the second movement "Gretchen" of his Faust Symphony, the first "Mephisto Waltz," the "Liebesträume No. 3," and the two volumes of his "Buch der Lieder."
