The device includes at least one cross-shaped element and a timbre square, which may be part of a larger, user-constructed sound emitter. Strung like beads along a fastener, one or more cross-shaped elements and timbre squares are arrayed between a bridge and terminal retainer. In one embodiment, the cross-shaped element and timbre square are juxtaposed, forming a sound emitter which is mounted within an F-hole instrument's sound chamber; the bridge, positioned above it and astraddle opposing F-hole side edges, collects inaudible sound surface waves and transmits them through the fastener—a knot-free, waxed string under tension—to the sound emitter. There sound waves are amplified by constructive interference, timbre characteristics added, and sound waves transferred into the sound chamber's air. The latter then increase the sound surface waves at the F-hole's edges, setting up a positive feedback loop.
