The Latin text of the mass is venerable, universal, and unites people. For the German Protestant Church Congress 2015, this ancient text was set in contemporary style by Tilman Jäger under the title Missa Pacis. Impressive sounds, mystic-meditative moods, Latin American rhythms, catchy melodies and a Dona nobis pacem for everyone to join in combine in the Missa Pacis to form a convincing whole. The hour-long composition is scored for 4–8 part chorus with optional soloists and accompanying band. The work is generally tonal, but offers a breadth of different styles ranging from classical choral-symphonic to rhythmic choral movements with influences from gospel, jazz, and pop. Parts for the accompanying band are fully written out. In some sections of the mass the instrumentalists can also improvise.
