I have heard some world famous guitarists playing some very difficult, rhythmic and beautiful pieces. But before you write the violin off because it only has 4 strings, please consider how those strings are played. If you really want to get it, get 3 recordings of world class violinists playing pieces like the Bach double violin concerto the Beethoven concerto. I think you have underestimated the dynamic range of the instrument, its ability to convey emotion, the nuances of bowing, trills and a score of other elements.
