The only items necessary for building the easy to assemble harp kit are glue and a screwdriver. There are two basic parts of the Waring Harp: the frame that defines the triangular shape of the harp, and the sound box for resonance. The sound box is die-cut in one piece from 3-ply corrugated cardboard. When painted, it is resistant even to rain. Treat it like any musical instrument and it will last many, many years. The hardwood frame is comprised of the string rib, pillar, and neck. Nineteen strings allow for over a two-octave range, enough to accommodate the playing of most any song. Zither pins (with tuning wrench) will provide tension for tuning the nylon strings.
