The violin was one of Bach's favourite instruments and inspired his most lyrical outpourings. We know he was greatly influenced by the Italian masters whose work he discovered during his Weimar years - by the power of Frescobaldi, the melodic flexibility of Corelli, the sunny grace of Vivaldi - but he developed his own wonderful artistry in writing music of polyphonic density for the violin and 'playing' with it's sound palette. His deep understanding of the instrument clearly enabled him to exploit it's full potential and to write as well as perform music of the utmost virtuosity.
