Wolfgang Amadeus Mozart uses trombones in connection with death or the supernatural. This includes the Requiem (K626, 1791), Great Mass in C minor (K423, 1783), "Coronation Mass (C major)" (K317, 1779), several other masses, "Vesperae Solennes de Confessore" (K339, 1780), "Vesperae de Dominica", his arrangement of Handel's "Messiah" plus two of his three great operas: "Don Giovanni" (K527, 1787) and "Die Zauberflöte" (K620, 1791). Mozart's first use of the trombone was an obligato line in the oratorio "Die Schuldigkeit des ersten Gebots" (K35, 1767)
