1. A musical instrument configured to receive strings and a bridge, the instrument comprising:
a back separated from a top by a rib structure to define an interior of the instrument; and
a soundpost within the interior and spanning between an inner surface of the back and an inner surface of the top, wherein:
the instrument is configured to receive the bridge positioned between the strings and an outer surface of the top to support the strings over the top;
the top and back are inherently flat;
when tension is applied in the strings such that the bridge applies force to the top and the soundpost applies force to the back, the top acquires a concave shape and the back acquires a convex shape.
