This is the third volume in an on-going series of books surveying the choral-orchestral repertoire. In this study, Green reviews Bach's entire oeuvre, including the more than two hundred works that are rarely performed and therefore rarely discussed. All Bach's works from BWV1 to BWV249 are analyzed, making this volume one of the most useful handbooks on this repertoire. Green reviews each work in great detail, providing information such as an instrumentation list, performance times, publishers, availability of materials, manuscript location (when possible), the hand of the copyist(s), text sources, a discography, and bibliographies specific to each composition. Most importantly, for each work there is a detailed description of the performance issues within the score. This includes evaluations of each solo vocal role, an evaluation of the choral and orchestral parts, along with an estimation of their respective difficulties. There are a number of indexes that provide brief biographical or historical information about each text source indexed back to the works themselves.
There is also an index of works by type, vocal solos, choral voicing, instrumentation, liturgical calendar, performance chronology, title, and chorale usage.
