In addition to the present piano reduction of the 1845 version , a Barenreiter edition containing violin parts and piano reductions of both the first and second versions is available as BA9050b. Having finished the first draft in Frankfurt in September 1844, Mendelssohn soon began to contemplate revisions, and in the following months consulted violinist Ferninand David about numerous details affecting the solo part. In December, in the midst of these discussions Mendelssohn's Leipzig publisher, Breitkopf & Hartel, commissioned a piano reduction of the orchestral score which Mendelssohn corrected and returned for the engraver on January 25th.
