The Düben Collection is the central source for the musical history of northern Europe in the second half of the seventeenth century. The unique, incomparable value of the collection lies both in its size – it contains nearly 2000 manuscripts and prints – as well as in its markedly international character. Düben compiled an extraordinary large and, in its artistic aspiration, singular repertoire of sacred and secular vocal music as well as, on a somewhat smaller scale, instrumental works, a repertoire that extended far beyond his regional sphere.
