ATB, SSATB, SSATB, 2 violin, viola, oboe, bass and keyboard continuo
Source: Oxford, Bodleian Library: 18th-century manuscript in score. Another of Lotti's impressive three-choir Kyries from San Marco.
Kyrie I uses two SATB choirs, each with SSA soli ensembles, and a 'coro palchetto' (balcony choir) comprising an ATB trio. The Christe section keeps the ATB palchetto choir, along with two choirs only of SSA. This may well be sung entirely as a solo section. The final Kyrie is a four-part fugue with only one SATB choir. Lotti uses this model for seven of his concertante Kyrie settings.
