Drawing on the riches of a largely unknown repertoire, this innovative makes available in modern score a large selection of Italian sacred music scored from printed part-books that have never before been published in modern editions. Each genre is organized for easy accessibility. Mass settings are presented in chronological order. Vesper and compline music is arranged according to the number of voices, chronologically within each volume, beginning with works for one and two voices and progressing to compositions for multiple choirs. Motets present individual works from the most significant collections, arranged according to composer, with special emphasis on the compositions of Alessandro Grandi.
