- Scholarly-critical performing edition - Six Suites for Violoncello solo - A unique edition - all readings at a glance This new edition, in contrast to the array of Bach Cello Suite publications available today, has made use of all the five sources which have come down to us. The basis for this edition is the most reliable of the sources, the manuscript copy in the hand of Anna Magdalena Bach. All variant readings from the four other sources are clearly laid out for performance. Cellists now have the possibility of rendering performances based on just one of the five sources as well as the option of combining the sources in a mixed version.
