The violin octet is a family of stringed instruments developed in the 20th century primarily under the direction of the American luthier Carleen Hutchins. Each instrument is based directly on the traditional violin and shares its acoustical properties, with the goal of a richer and more homogeneous sound. Unlike the standard modern stringed instruments, the main resonance of the body of the violin octet instrument is at a pitch near the two middle open strings, giving the instruments a more balanced, clearer sound.
