This is the acoustic guitar that mounts over a doorway and plays a chord of one’s choice when a door is opened or closed. A fully playable 1/2-size acoustic six-string, the guitar mounts above a door with the included mounting hardware with the strings facing down. A plectrum fixed to a flexible spring mounts to an inward-swinging door, such that when the door is opened or closed, the plectrum sweeps across the strings to play a chord. The included pitch pipe and chord chart are keyed to enable tuning to a chord that fits the day’s mood or a portal’s intended use, whether a major that welcomes expected company, a pensive minor seventh that “guards” a teen’s bedroom, or a complex diminished when anticipating an in-law that often arrives unannounced via a back door. The guitar has a spruce laminate top, solid rosewood bridge and fingerboard, and sapele neck, allowing normal play when removed from the mounting board with the included re-usable fasteners. Guitar extends 11 1/4" from wall; mounting board 30 1/2" L x 4" H x 3/4" D. (8 lbs.)
