The Viola da Gamba Concerto in F Major by Johann Carl Graf zu Hardeck comes from the Ledenburg Collection in which another three viola da gamba concertos have been preserved (Milling, Raetzel, and Abel). Unfortunately, we know practically nothing about Hardeck, except that he participated in an opera performance at the Viennese imperial court in 1724. No other compositions by him are known. The Concerto does not make any special demands on the performer, but shows itself, in spite of its simple structure, to be an appealing chamber music work that places the viola da gamba in the limelight.
The Ledenburg Collection in Osnabrück was discovered only in 2015. For the most part, it is made up of viola da gamba music of the early Classical era.
