This new edition contains all the Chorales from Schemelli's song book in their original Order. Compared with the former Edition Breitkopf No. 730 which was a standard Performance edition for over one hundred years this new edition has been printed in a larger format and type. This as well as the addition of the first stanza of each Chorale in the musical text makes the Spiritual Songs and Arias still easier to use. The two-part pieces with figured bass have been maintained in the original form which allows the Performer to work out his own realization.
