Frets

The frets are made of loops of gut tied around the neck. They fray with use, and must be replaced from time to time. A few additional partial frets of wood are usually glued to the body of the instrument, to allow stopping the highest-pitched courses up to a full octave higher than the open string, though these are considered anachronistic by some (though John Dowland and Thomas Robinson describe the practice of gluing wooden frets onto the soundboard). Given the choice between nylon and gut, many luthiers prefer to use gut, as it conforms more readily to the sharp angle at the edge of the fingerboard.
