Wolfgang Rehm (3 September 1929 – 6 April 2017)[1] was a German musicologist active mostly in music publishing, especially the Neue Mozart-Ausgabe.

Born in Munich,[1] the son of Walther Rehm, Wolfgang studied musicology from 1948 to 1952 at the University of Freiburg (subsidiary subjects: modern German literary history and medieval history) and graduated in 1952 with a work on the chanson work of the Franco-Flemish composer Gilles Binchois.

[1][2] From 1952 to 1954, Rehm worked as a trainee at the music publishing house Breitkopf & Härtel in Wiesbaden and began on 1 May 1954 as a research assistant and editor at Bärenreiter in Kassel, initially with a focus on complete editions, such as the Neue Mozart-Ausgabe (NMA) in 1955.

[2] Rehm was the chief editor of Bärenreiter from 1971, and from 1975 a member of the management board with responsibility for book and music production.

[1][2] From 1959 to 2002, Rehm was a member of the boards of various specialist and artistically oriented societies and associations, including the Gesellschaft fur Musikforschung, the Internationaler Arbeitskreis für Musik, and the International Association of Music Libraries, Archives and Documentation Centres (IAML), which he served as treasurer from 1959 to 1985.
