Contrabassoon - Differences From The Bassoon

Differences From The Bassoon

The reed is considerably larger, at 65–75 mm in total length as compared to 53–58 mm for most bassoon reeds. Fingering is slightly different, particularly at the register change and in the extreme high range. The instrument is twice as long, curves around on itself twice, and, due to its weight and shape, is supported by an endpin rather than a seat strap. Additional support is sometimes given by a strap around the player's neck. A wider hand position is also required, as the primary finger keys are widely spaced. The contrabassoon has a water key to expel condensation and a tuning slide for gross pitch adjustments. The instrument comes in a few pieces (plus bocal); in some models, it cannot be disassembled without a screwdriver. Sometimes, however, the bell can be detached, and in the case of instruments with a low A extension, the instrument often comes in two parts.
