As I already said, sometimes Vallet uses hold lines on empty strings.
Here is an example: In "La Courante Sarabande" (CNRS No. 74, page 177 or original source page 83) in bar 21 (first bar in 3rd stave in the original) there is a hold line starting on the open 6th course. I think it should start on the 3rd chord which has no hold line. Rainer To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
