Franz Xaver Süssmayr

Franz Xaver Süssmayr (also Süßmayr, or Suessmayr in English; 1766 – September 17, 1803) was an Austrian composer and conductor. Popular in his day, he is now known primarily as the composer who completed Wolfgang Amadeus Mozart's unfinished Requiem. In addition, there have been performances of Süssmayr's operas at Kremsmünster, and his secular political cantata (1796), Der Retter in Gefahr, SmWV 302, received its first full performance in over 200 years in June 2012 in a new edition by Mark Nabholz, conducted by Terrence Stoneberg. There are also CD recordings of his unfinished clarinet concerto (completed by Michael Freyhan), one of his German requiems, and his Missa Solemnis in D.

Works
His works include the following:
 * String Trio in D Minor (SmWV 613)
 * Two masses (SmWV 101–102)
 * Two requiems (SmWV 103–104)
 * Seven offertories (SmWV 112–115, 117–119, 123, 125, 144–145, 156)
 * A gradual (SmWV 143)
 * Psalms
 * A magnificat
 * Hymns
 * Agonia e morte di Mozart (fantasia for piano)
 * Nicht mehr als sechs Schüsseln (SmWV 205)
 * Moses oder der Auszug aus Ägypten (SmWV 209)
 * Der Spiegel von Arkadien (SmWV 213)
 * List und Zufall (SmWV 224)
 * Soliman oder die drei Sultaninnen (SmWV 219). Beethoven used a theme from this opera for his Variations on 'Tändeln und Scherzen', WoO 76.

Of special note may be the clarinet concerto (SmWV 501) he most probably wrote for Mozart's clarinetist Anton Stadler, because it was scored for the basset clarinet. Recordings of the work by Dieter Klöcker (on Novalis) on "normal clarinet" and by Thea King (on Hyperion) in a reconstructed version for basset clarinet by Michael Freyhan are available. In 2021 a completion appropriate for period basset clarinet was published by Craig Hill.

Ballet

 * Il noce di Benevento, ballet by Salvatore Viganò, premiered at La Scala on 25 April 1812. It gave an inspiration to Niccolò Paganini for creating Le Streghe, Variations on a theme from the ballet Il noce di Benevento (Op. 8, 1813).
