The Missa opportuna is – as the title suggests, a short, compact, easily singable Mass suitable for all occasions in the liturgical year. It combines the Latin Mass text with a timeless, classical a cappella choral setting that can be supported instrumentally colla parte, if required. The Kyrie and Gloria as well as the Sanctus and Agnus Dei are thematically linked and yet independent in terms of their musical mood: the Kyrie call is followed by a rousing Gloria and the Sanctus appears solemnly borne. The Agnus Dei intensifies towards the end to an impassioned plea for peace. Musically, the final section takes up the motif of the beginning of the Kyrie again, thus ensuring a cyclical unity. An immediately catchy, impressive Mass for many occasions!
