Wurstfagott (sausage bassoon) and Büchsentrompete (box trumpet)

The rankett or rackett, a wind instrument predominantly of the 17th century, has been preserved in only a few examples. Its body is formed like a can and contains a spiralled drill. Therefore the tube inside is nine times longer than the can. The folded tube has been associated with sausages, which is why the instrument is also called a sausage bassoon. The rankett has its timbre in common with the bassoon, as well as the bass register and the double-reed. Etymologically the term rankett likely derives from the Upper German »rank«, which means crook or bend.

At the beginning of the 17th century, Michael Praetorius described the rankett as follows: »In resonance ranketts are quite soft, almost as if one were blowing through a comb. They have no particular grace when a whole consort of them is used together; but when viols da gamba are used with them, or when a single rackett is used together with other wind or stringed instruments and a harpsichord or the like, and is played by a good musician, it is indeed a lovely instrument. It is particularly pleasing and fine to hear on bass parts.«

The construction principle of the box trumpet was similar to that of the rankett: the instrument maker strived to construct a handy and at the same time euphonious musical instrument. The tube of the trumpet inside the can, which is shaped like a truncated cone, is bent in eight turns from top to bottom. From the bottom, the tube is then bent upwards again within the spiral and after two more nearly right-angled bends it opens out into the bell, which opens downwards. The available space is perfectly used.
