Double Bass - Design

Design

In general, there are two major approaches to the design outline shape of the double bass: the violin form (shown in the labelled picture to the right); and the viol da gamba form (shown in the header picture). A third less common design, called the busetto shape, can also be found, as can the even more rare guitar or pear shape. The back of the instrument can vary from being a round, carved back similar to that of the violin, to a flat and angled back similar to the viol family.

The double bass features many parts that are similar to members of the violin family, including a bridge, f-holes, a tailpiece, a scroll, and a sound post. Unlike the rest of the violin family, the double bass still reflects influence, and can be considered partly derived, from the viol family of instruments, in particular the violone, the bass member of the viol family.

The double bass also differs from members of the violin family in that the shoulders are typically sloped, the back is often angled (both to allow easier access to the instrument, particularly in the upper range), and machine tuners are always fitted. Lack of standardization in design means that one double bass can sound and look very different from another.
