2. GLORIA, Op.18 (ca.10') for a cappella SATB Double Choir, with 2 x SA Soloists. (There is the option to double the solo parts, if necessary.) The eight main vocal lines are sometimes further divided for fullness of texture and motivic completeness.
(* But ideally at least double these forces: 16 per choir, or 32 for the two choirs + 4 soloists [the parts of which may be doubled to 8 singers] = 40 singers).
BOTH WORKS ARE BASED ON THE SAME CHORD SEQUENCE.
