Lemberg. He did not give up performing and in the years 1819 to 1821 traveled throughout Europe. In 1819 he gave concerts in Warsaw, Elbing and Danzig (Gdańsk). In the 1820s, Mozart was one of 50 composers to write a variation on a theme of Anton Diabelli for part II of the Vaterländischer Künstlerverein. Part I was devoted to the 33 variations supplied by Beethoven which have gained an independent identity as his Diabelli Variations Op. 120. Around that time, Mozart made the acquaintance of Schubert and the two became close until Schubert’s 1828 death. In 1838 Mozart left for Vienna, and then for Salzburg, where he was appointed as the Kapellmeister of the Mozarteum. From 1841 he taught the pianist Ernst Pauer. Mozart died from stomach cancer on 29 July 1844 in the town of Karlsbad (now Karlovy Vary) where he was buried. Like his brother, he was unmarried and childless. His will was executed by Josephine de Baroni-Cavalcabò (1788–1860), a longtime patron to whom he dedicated his cello sonata. The shadow of his father loomed large over him even in death. The following epitaph was etched on his tombstone: "May the name of his father be his epitaph, as his veneration for him was the essence of his life." Works by genre Franz Xaver Wolfgang had a relatively small output (his opus numbers only go up to 30) and after 1820 he seems to have given up composing almost entirely; in particular, there is an 11-year gap (1828 to 1839) when he seems to have not written anything. Nevertheless, recordings of his music can be found today. He wrote mainly chamber music and piano music, with his largest compositions being the two piano concertos. Orchestral works Sinfonia Overture in D major Concertante Piano Concerto No. 1 in C major, Op. 14 (1808, published in 1811) Piano Concerto No. 2 in E-flat major, Op. 25 (1818) The two piano concertos differ somewhat. The first concerto could pass for one of his father's late (K. 550 and above) works, except for a youthful exuberance and the piano's tessitura which had been expanded in 1795, just after Mozart senior died. The second concerto is more contemporary to the 1810s with a more virtuosic piano part showing hints that the younger Mozart was developing his own style.
