Under the title of 'Kleinere Werke' [Minor Works], the second volume of organ works by C.Ph.E.Bach in the Wiener Urtext Edition contains all works written by the composer except for the multi-movement sonatas for organ. The fugues, in particular, prove that C.Ph.E. Bach was an attentive pupil of his father. The pieces for musical clock are a varied selection of pieces in the style galant which were originally written for mechanical instruments and which are best to be performed on the organ. Together with the organ sonatas published in Vol.1, this is probably the most comprehensive collection of works by Bach's second eldest son which can be performed on the organ.
