For the new Barenreiter edition, the Mendelssohn specialist R. Larry Todd edited both the original version of the concerto as well as the later version known today. The first version of the concerto contains a shorter cadenza by Mendelssohn and calls for the soloist to perform the tuttis. Two copies of the violin part are provided, one Urtext and one with fingerings and bowings. A separate edition of the 1845 Second Version is available as BA9050 90. 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.
