From a Requiem in E flat major, the most likely dates from the period 1772-1775, three historical copies have been preserved, namely in the Episcopal Zentralbibliothek Regensburg, in the Cathedral Library Freising and in St. Peter's Monastery in Salzburg. The work is composed for four soloists, four-part mixed choir ( SATB ), Violin, Viola, 2 horns or (in the Dies Irae ) trumpets, timpani and organ.
