This work examines the structural and aesthetic composition of Emanuele d'Astorga's eighteenth-century choral setting of the Stabat Mater. The text serves as a critical edition prepared by Robert King, who utilizes period-accurate sources to reconstruct the nine-movement work for modern performance by SATB soloists, chorus, and string ensemble.

Experts and choral directors recognize this edition as a standard resource for performing d'Astorga's historically significant composition. The inclusion of an organ reduction is frequently cited as a practical benefit for ensembles preparing the work for performance.
