Three of his harpsichords survive: A plain single-manual instrument, preserved
Hudiksvall, Sweden, is signed 'Berlin, 1710'. In
Schloss Charlottenburg in Berlin there are two instruments, both probably made for the court. Both are unsigned, although they have been linked to Mietke beyond reasonable doubt. One is a single-manual, which belonged personally to
Queen Sophie Charlotte, and the other a double-manual. Both are lavishly decorated by the court decorator
Gerard Dagly: the single manual instrument, covered with gilded
chinoiserie on a porcelain white background, earning the instrument the affectionate modern nickname "The White Mietke", while the double manual instrument is in similar style, but on a black background and thus often referred to as "The Black Mietke". ==Progeny==
