Johann Adam Joseph Karl Georg Reutter, during his life known as Georg Reutter the Younger (6 April 1708 – 11 March 1772) was an Austrian composer. According to David Wyn Jones, in his prime he was "the single most influential musician in Vienna". Early life Reutter was born and died in Vienna. His father Georg Reutter (the Elder) was also a notable composer. He was the 11th of 14 children and received his early musical training from his father, assisting him as court organist. A period of more formal instruction from Antonio Caldara ensued, leading to the composition of an oratorio in 1726 and, in 1727, his first opera for the imperial court, Archidamia. On three separate occasions during this period, Reutter applied for a position as court organist and was each time rejected by Johann Joseph Fux. At his own expense he travelled to Italy in 1730 (possibly in 1729); in February 1730 he was in Venice and in April 1730 in Rome. He returned to Vienna in autumn 1730, and early in the following year he successfully applied for a post as court composer, the formal beginning of a lifetime of service at the Habsburg court. After his father's death he became Kapellmeister of St. Stephen's Cathedral in 1738. As Kapellmeister The Kapellmeister position had existed since the fifteenth century and Reutter was the 27th to occupy the post. The job provided living space directly adjacent to the cathedral, the Kapellhaus (demolished in 1803), which also housed Reutter's family and the choirboys. Reutter supervised a staff of 31 musicians, as follows: 5 choirboys, who sang the treble (soprano) part 12 adult male singers: basses, tenors, and countertenors. The latter sang the alto part. 12 string players an organist a subcantor, who assisted Reutter When trumpets, timpani, or trombones were needed, they were recruited on an ad hoc basis, often borrowed from the musical establishment of the imperial court (Hofkapelle). According to Jones, the repertoire of church music "constituted a continually unfolding tradition that is poorly served by the familiar division of the [18th] century into Baroque and Classical." Much of this repertoire was by Reutter himself (see Works, below); other composers prominently represented were Bonno, Tuma, and Fux. Reutter and Haydn In 1739, while visiting the town of Hainburg, Reutter auditioned the seven-year-old Joseph Haydn; Haydn joined his ensemble the following year, later to be joined by his
