Bachmann was one of an energetic group of publishers in the former Kingdom of Hannover and Duchy of Brunswick, (present day Lower Saxony) such as Nagel (Hannover), Litollf and Heinrichshofen (Braunschweig) and Möseler Verlag (Wolfenbuttel).
Christoph Bachmann started a musical goods store, lending library, and publishing company in Hannover in 1819. At some point in the 1820s he went into partnership with local businessman (Georg Wilhelm) Adolph Nagel (1800–1873), publishing under the name Bachmann & Nagel until the end of 1834. In 1835 he sold the store and library to Nagel, but continued publishing.
However, in the long run, Nagel was more famous, operating independently until 1950, and respected by amateur players for its blue-covered Nagel's Musik-Archiv series (1927-).
Bachmann's firm was a success, becoming one of the longest surviving small publishers, functioning for nearly 100 years. The catalog was typical of the period: piano pieces and songs; pieces for cello (Friedrich August Kummer and Karl Matys), violin (Chr. Muller and Heinrich Wilhelm Ernst), and horn (Karl Daniel Lorenz); and at least one opera by Heinrich Marschner.
Bachmann's plate numbers appear in the format of #### and appear to have been issued in a fairly regular chronological fashion. Dates in italics are estimated. (Not wholly regular; plate 1332, for instance, belonging to 3 J.L. Dussek duet sonatas, seems to have been issued around 1825.)
