Some Construction Details
This photo shows a typical Cunningham harp soundbox with its round back and in-curved edges. The narrow and rounded upper end rests very comfortably on the harp player’s shoulder and feels good for the hands as there are no wide or sharp edges. The bass end of the box flares slightly to enhance the lower range (like a lute body).
My harp necks are all constructed from two pieces of solid wood, finger-joined at the greatest curvature. Some years ago I began inlaying a brass plate beneath the harmonic curve and since then have not seen a single case of neck breakage even when a harp falls over (almost always a disaster for the harp neck!). The photo below shows an example of a prepared neck and mortised column attachment.
