In 2012 Carus-Verlag launched the series Bach-Repertorium to make available for study and performance the compositions of all members of the widespread Bach family of musicians from the 17th into the 19th century.
For the first time, as a result of systematic research covering all musical and archive sources, all compositions attributed to members of the Bach family will be categorized according to the same criteria. In addition to details of scoring, succession of movements, and history of the works and sources, information is given concerning editions, authentication, and the most important literary references.
In the case of vocal works the origins of the texts, editions of the librettos, and the chorale melodies used are verified. Also covered are arrangements of works by other composers, editions with which the composer was involved, and—as far as it can be reconstructed—his music library.
An appendix includes arrangements by others, and spurious works are also described. The accompanying music examples document in short score the beginning of each movement and the structurally important sections of the compositions, providing for an initial insight into the works. The use of the volumes is facilitated by numerous indices.
