NEUPERT fortepiano after Dulcken

 NEUPERT fortepiano 
after Louis Dulcken (Munich, c.1815)

Louis Dulcken was a descendent from a family of well known instrument makers. His grandfather Joannes Daniel Dulcken, who was active in Antwerp and Brussels, was considered as "the best harpsichord maker in succession to the three Ruckers" according to contemporary opinion. His grandson Johan Lodewijk Dulcken, born in 1761 in Amsterdam, set up business in 1781 in Munich, where under the name of Louis Dulcken he achieved high esteem as a pianoforte maker to the court.

The NEUPERT copy is based on an original instrument made by Dulcken in around 1815, which was in our ownership. This fortepiano, like a modern instrument, is equipped with a forte and an una corda pedal. Moreover there is a moderator pedal which allows one to perform the markings "sordina" or "pianissimo" in accordance with the piano literature of that time. The clear and also flexible sound of this fortepiano, as well as the light action, destine this NEUPERT instrument to be an ideal mediator between the periods of classical and early romantic piano music.
