Franz Xaver Wolfgang Mozart Franz Xaver Wolfgang Mozart

Franz Xaver Wolfgang Mozart (26 July 1791 – 29 July 1844), also known as Wolfgang Amadeus Mozart, Jr., was the youngest child of six born to Wolfgang Amadeus Mozart and his wife Constanze. He was the younger of his parents' two surviving children. He was a composer, pianist, conductor, and teacher from the late classical period whose musical style was of an early Romanticism, heavily influenced by his father's mature style.

Works (selected)

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.

• Piano Quartet in G minor, Op. 1 (published 1802)
• Cantata for the Birthday of Joseph Haydn, lost (1805)
• Sonata for Violin and Piano in B-flat major, Op. 7
• Piano Sonata in G major, Op. 10
• 6 pieces for Flute and 2 Horns, Op. 11
• Piano Concerto No. 1 in C major, Op. 14 (1808, published in 1811)
• Sonata for Violin and Piano in F major, Op. 15
• Six Polonaises mélancoliques for piano, Op. 17
• Sonata for violoncello or violin and piano in E major, Op. 19 (published in 1820)
• Quatre Polonaises mélancoliques for piano, Op. 22
• Five Variations on a romance from Méhul's Joseph, Op. 23 (pub. 1820) (until 1994 mistakenly attributed to the young Liszt, S147a)
• Two Polonaises for piano, Op. 24
• Piano Concerto No. 2 in E-flat major, Op. 25 (1818)
• Der erste Frühlingstag (The First Spring Day), cantata for solo, choir and orchestra, Op. 28
• "Festchor" for the unveiling of the Mozart monument in Salzburg, Op. 30 (1840)
• Sinfonia
• Rondo in E minor for flute and piano
• Songs with piano accompaniment

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.
