A neck for a stringed musical instrument may include a generally longitudinal center support member with a fingerboard fixed thereto. The center support member may be fixed at one end to a string mounting member and fixed at an opposite end to a body of the stringed musical instrument. A generally longitudinal tension adjustment member may be fixed at one end to the string mounting member and fixed at an opposite end to the body of the stringed musical instrument. The tension adjustment member may be adjustable to vary stress on the neck. A generally longitudinal spatial volume may be located between the center support member and the tension adjustment member. A majority of the spatial volume may comprise ambient air.
