Ave Verum Corpus (8Pos) (Mozarts wonderful setting of the Eucharistic hymn Ave Verum Corpus was composed in June 1791. It was dedicated to his friend, Anton Stoll, who was chorus master of the parish church in Baden, and was first performed in Baden at the Feast of Corpus Christi. This arrangement is for double quartet of trombones, or trombone choir, of intermediate standard and the tenor trombone parts are supplied in both Bb treble and bass clefs.)
