A four-string violin, viola, cello or doublebass with a
standard fingerboard. On violins it should have a thickness of about 4,5 mm at the end of the fingerboard.
"Projection", the angle neck to body, should be normal. On violins the distance between mid-body and upper edge of the end of the fingerboard should be approximately 21 mm.
