A dampening bar assembly comprised of a pair of support blocks held in parallel spaced-apart relationship by a pair of transverse frame members attached between the support blocks at each end of the support blocks forming a rigid rectangular frame. A number of dampening bars including string vibration dampening pads mounted to the bottom side of each dampening bar are slideably mounted parallel to each other transversely between the support blocks in vertical slots formed in the opposing support block sides. Compression springs mounted in cavities formed in the bottom of each slot provide an upwardly urging force on each end of the dampening bars. Each support block includes a lengthwise aperture therethrough for receiving a square hardwood rod to retain the compression springs in a compressed configuration to provide for assembly and disassembly of the dampening bar assembly. The dampening bar assembly is designed to be used with a stringed instrument such as an auto harp. The note bars are arranged in adjacent fifth-tones or in a similar pattern to provide ease and consistency of chording and are spaced to provide effective operation without raised finger-buttons or pads requiring on the fingering surface of the note bars. The dampening bar assembly forms a complete and self-contained unit which may be retrofitted to existing instruments.
