This edition of Alessandro Scarlatti's finest and most extended piece of liturgical music presents it for the first time in a full score which aims to meet the requirements of both the performer and the scholar. The Mass was composed for the St Cecilia's Day celebrations in Rome in 1720. It is an example of Scarlatti's most mature style, auniquee combination of brilliant vocal and instrumental techniques that he had developed in the cantata and opera with the learned yet unpedantic counterpoint which he had held in such high esteem throughout his life. For SSATB soli and chorus, string orchestra and organ continuo. Edited by John Steele. Vocal score with organ part.
