Brandenburg. Konz. 5 D BWV1050

...These new editions were based on surviving autographic source material - some of which, for the Fifth Concerto for example, has been taken into account for the first time - and the ’Neue Bach-Ausgabe’ (NBA). Moreover, they also make use of relevant 18th-century theoretical writings for editorial additions and observations on performance practice.” (from the joint preface to the “Six Brandenburg Concertos” by the Bach scholars Werner Felix, Winfried Hoffmann and Armin Schneiderheinze)
