The Kyrie in G minor (RV 587) by Antonio Vivaldi is a setting of the Kyrie for two cori (two orchestras, each with respective four-part chorus) written between 1720-35.
This is the only extant setting of the Kyrie the composer wrote.
The chorus is adorned with descending quavers in the orchestra.
The final movement unites the two cori with a brief grave and enters a fugue.
The fugue would later be reworked for the composer's Concerto Madrigalesco (RV 129).
