Abstract
In a conventional stringed musical instrument the nut, the bridge and the fingerboard are either all radius or all flat. Bowed instruments such as cellos and violins require radius structures so that single note melodies can be played on the middle strings. But for some players the radius fingerboards are a bit harder while playing melodies. Classical and flamenco guitars have flat nut, bridge and fingerboards for ease of plucking and strumming the strings close to the bridge. However, flat fingerboards are harder to bar for playing cords. [Delete paragraph mark and indent] Combinations of flat nut with radius bridge and radius nut with flat bridge can be used if the fingerboard surface is changed to have a specific 3-dimensional curvature and may be preferred for their playability by some players.
