Viola d'amore
The viola d'amore is about the same size as a modern viola. However, the shape is more like the shape of a viol. Like viols, it has a flat back, a wide rib (the sides), sloping shoulders and a carved head at the top of the peg box. It does not have any frets (markings on the fingerboard) like a viol or a guitar. The sound-holes are often in the shape of a flaming sword.
