The New Bach Edition (NBA), now completed and available in 104 music volumes and 101 critical commentaries, is regarded as a work of musical scholarship of the first rank. The publication of this immense project stretched over 56 years. However, since the publication of some of the earlier volumes, new sources have been discovered and others newly evaluated, new knowledge has been acquired and further editorial experience amassed. In the interest of a continued practical and musicological usability of the historical scholarly-critical complete edition, it is essential to update selected volumes.
The Bach Archive Leipzig and Bärenreiter have therefore decided to publish approx. 15 volumes or works in revised editions. The New Bach Edition – Revised (NBArev) resembles the NBA in its outward appearance, but each volume now contains a more detailed foreword in German and English, discussing the genesis of the works and how the sources have come down to us as well as a concise critical report in German.
The Bach Archive Leipzig is the internationally recognised centre for Bach research. This guarantees that the New Bach Edition – Revised will be prepared by first-class editors. Volume by volume, editions of the highest standard will be created for the NBArev.
The Mass in B minor will be the first work to be published during the summer of 2010. This work was originally published in 1954 (edited by Friedrich Smend) as the second volume of the NBA. The revised edition, edited by Uwe Wolf (Bach Archive Leipzig), takes into consideration the results of the latest research and scientific examination methods (x-ray spectography) into Bach’s manuscript score.
