The Five String Violin is a descendant of the traditional four string violin. In the last five years, the five-string has gone from being a rare anomaly to a viable option for many string players. The sound produced by a 5 string violin is clear, deep and rich, acoustic violin voice with lots of tonal personality. The great thing about the 5 string violin is its accessibility, it provides an entirely new, incredible sounding instrumental voice to the violinist while retaining the same note locations. The role that a 5-string can play as a supportive instrument is incredible compared to that of a 4-string. It supports a low instrument like guitar during solos far better. The low range sound that the five produces, makes the accompaniment sound better and more effective.
Havinf described all about the unique characteristics of a 5 string violin there are some who do complain that the tuning of the five string is quite difficult. And of course playing the 3 or 4 string violin is much more easire that playing the 5 string.
