Spatzenmesse. Par MOZART WOLFGANG AMADEUS. An unusual feature of this Mass is its cyclic form, a compositional principle which Mozart first introduced in his masses in this 'Mass in C': in the Agnus Dei ('Dona nobis pacem') he reverted to the music of the Kyrie, thus giving the Mass overall musical unity. Another unusual feature of this work is its popular character. This is evident both in its catchy themes and in its relatively straigthforward musical structure. / Messe / Répertoire / Solistes SATB, Choeur SATB, 2 Clarinettes, Timbale
