Renaissance-Raketts  have a 9-fold bore – the single joints are connetced on the top and the botton changewise, so that it makes a tube 9 times as long!
So the short and squat instruments sounds astonishingly deep; the bass goes just down to CC!

Racketts requires a very big and broad double reed, and are blown traditionell with a pirouette.
The sound is reedy, full, droning, but rather quiet due to the narrow and folded bore and 

Racketts may be used as a whole consort ATTB in the 16-foot stave.
The compass is one and a half octave, with suitable reeds, one or two notes may be overblown.

Alto C – a
Tenor G – e
Bassett F – d
Bass C  - A

Also a single rackett is very effective as a contrabass in a quiet consort, as recorders / flute, viols or voices
The bassett rackett has the most suitable compass for this.

Front- and backside

The very special inner construction makes a special fingering too: 10 fingers have to cover 11 holes!
For this, both thumbs are required, and the inner parts of the index fingers.

With some training, the fingering can be mastered easyly, and the instruments lies perfect in the hands, even in small ones.
