A musical instrument neck stiffener includes a beam fabricated by embedding uni-directional material only at the upper and lower portions of the beam, and constrained by braid or bias weave material. In a preferred embodiment, the uni-directional layers are preferably made from carbon fiber tow, cloth, or pultruded carbon fiber and the braid or bias weave material is made of carbon fibers. To reduce weight, the middle section of the beam is preferably hollow. An angle neck stiffener includes a hollow tube connected to a cradle, which is bonded within an instrument neck. The angle neck stiffener bridges the connection between the instrument neck and a preferably D-shaped neck stiffener.
