The Missa Salisburgensis à 53 voci is a large-scale Baroque mass setting in the style of Venetian polychoral music. The composition, which has survived anonymously, is now attributed to Heinrich Ignaz Franz Biber. The mass was probably first performed in Salzburg Cathedral in 1682 on the occasion of the 1100th anniversary of the bishopric of Salzburg. The ensemble Concerto Stella Matutina performs with two vocal choirs, two string choirs, a large continuo, flutes, oboes, cornetts, trombones and 10 trumpets with two timpani.
