Bach's Concerto for two violins in D minor, BWV1043, affectionately known as the 'Double Concerto', is one of the most popular works of the Baroque repertoire. The two solo parts of this concerto have survived in Bach’s own handwriting, in an autograph that dates from around 1730, when Bach was living in Köthen. The outer movements illustrate the influence of the Italian Baroque style on Bach in their brisk rhythms, fugal imitations and much of the intricate passage work, while the central movement is deeply expressive as the melodic lines weave between the two violins.
