The Five string violin is a descendant of the traditional four string violin. It consists of a violin-shaped body, neck and pegbox, slightly exaggerated to fit a fifth string.
The usual five string violin combines the strings of the violin (G, D, A, E) and the viola (C, G, D, A) as C, G, D, A, E.[1] Some five string violins are strung: F, C, G, D, A. (Six- and seven-string electric violins also exist, adding lower strings tuned to F and B♭.)
