It sets a sequence of eight non-liturgical German poems by Johann Philipp Neumann, who commissioned Schubert's music, one or more of which could be used separately during Mass.
A ninth hymn, given as an appendix, treats the Lord's Prayer, bringing the length to about 35 minutes when the music is performed, as it often now is, as one big concert work.
Decades after Schubert died, a grander edition was published: SATB choir, 2 oboes, 2 clarinets, 2 bassoons, 2 horns, 2 trumpets, 3 trombones, timpani and basso continuo.
[1] The Deutsche Messe stems from a tradition of low masses, settings of religious texts in vernacular languages in Austria and southern Germany.
Most of the work is set in a moderate (mäßig) to slow (langsam) tempo, reflecting the solemnity of the service as well as consideration of church acoustics.
