A leading eighteenth-century composer, Sammartini was a key figure in the creation of the classic style, particularly the classic symphony. His symphonies and sonatas have survived in greatest number, but of equal interest is the sacred vocal music, a product of his lifelong service as a church musician. This volume lists all Sammartini's known orchestral and vocal works, sacred and secular—286 items. The entries give an incipit of each movement; instrumentation; date if known; a list of early manuscript and printed copies; and other significant information about variants, circumstances of performance, singers, copyists, and the like. The appendices list arrangements, contrafacta, and lost, doubtful, and spurious works.

Music collections in more than seventy-five libraries have been examined in gathering this material. Most compositions are listed here for the first time. In their introduction the authors provide a detailed biography, and discuss the composer's style, the major manuscript sources, and problems of authenticity. They have also included an extensive bibliography. Their book is basic to any study of Sammartini and of this pivotal period in the history of Western music.
