H. Grenser six/eight-keyed flute, 430 Hz

around 1790

Heinrich Grenser (born Lipprechtsroda, Thuringia, 1764; died Dresden, 1813)

The original, a very early, multi-keyed ebony and ivory transverse flute with interchangeable D and C footjoints, has survived in a private collection in Germany. The keys, which are very large, are hand forged of silver. The Grenser mark, with swords, dates the instrument as pre-1807.

The model in box wood displays a variation with divided F key: long and short F keys act independently and control individual holes. This variation was used by Grenser in other flutes.
