Abstract: Conventional stringed musical instrument fingerboards are constructed with a constant longitudinal slope, relative to the string, along the fingerboard's length direction. Fingerboards with variations in their slope along their length direction could improve playability by shortening the string-to-fingerboard distances. A variable slope fingerboard is suggested to improve playability at locations close to the bridge.
Abstract: The conventional musical instrument top and back plates are supported with straight and scalloped braces. These braces tend to dampen vibrations along the length direction of the brace. Kerfed braces are introduced to mitigate the damping. If glued with their kerfed edge to the top or back plates they mitigate damping without much compromise in their strengthening properties.
