Abstract: In a finger plate for a stringed instrument, the frets are formed arcuately and have a center of curvature through which some extending lines of strings pass, so that lengths of the strings between adjacent frets are made equal and every string crosses every fret perpendicularly. As a result, exact musical interval can be attained.
