There are 38 works in the Neumeister Collection that are generally attributed to Bach. This collection of 82 items by several composers, including other Bach family members, was rediscovered only in 1985 by musicologist/organist Christoph Wolff. Some musicologists have doubted the authenticity of a few of the works in it that have been attributed to Bach, but there is little doubt that this chorale prelude, "Erhalt uns, Herr, bei deinem Wort" (Lord, keep us steadfast in Thy Word), was written by him. Another chorale prelude by the same title, however, BWV Anh. 50, is of doubtful provenance. BWV 1103 is an attractive fughetta whose expressive manner is relatively simple. On its first appearance, the chorale theme is played almost completely through in single notes in the middle register, with no accompaniment. Thereafter, Bach treats it fugally, the accompanying material often coming from a much lower range on the keyboard. There is scarcely much development and the contrapuntal writing, while well crafted, does not exhibit the innovative character Bach would routinely divulge in so many later compositions. This work typically has a duration of two minutes.
