The Concerto for Two Violins in D minor, BWV 1043, also known as the Double Violin Concerto, is a violin concerto of the Late Baroque era, which Johann Sebastian Bach composed around 1730. It is one of the composer's most successful works. History Bach composed his Concerto for Two Violins in D minor, BWV 1043, around 1730, as part of a concert series he ran as the Director of the Collegium Musicum in Leipzig. Structure The concerto is characterized by a subtle yet expressive relationship between the violins throughout the work. In addition to the two soloists, the concerto is scored for strings (first violin, second violin and viola parts) and basso continuo. The musical structure of this piece uses fugal imitation and much counterpoint. The concerto comprises three movements: Vivace in D minor Largo ma non tanto in F major Allegro Performance time of the concerto ranges from less than 13 minutes to over 18 minutes. Reception Around 1736–1737 Bach arranged the concerto for two harpsichords, transposed into C minor, BWV 1062. 1734–1738 Carl Philipp Emanuel Bach performed the concerto in Frankfurt an der Oder. After his father's death in 1750, Carl Philipp Emanuel inherited some of the original performance parts, likely doubles, of the concerto (surviving: parts for soloists and continuo), and likely also the composer's autograph score (lost). The extant original parts were later owned by , and were added to the Royal Library at Berlin (later converted to the Berlin State Library) in the 1840s. After the Second World War they were lost for several decades, eventually resurfacing in Poland. Manuscript copies of (parts of) the concerto were produced around 1730–1740, in 1760, around 1760, around 1760–1789, and in the early 19th century. The concerto was first published in 1852, by Edition Peters, edited by Siegfried Dehn. In the first volume of his Bach biography (1873), Philipp Spitta describes the concerto as a product of the composer's Köthen period (1717–1723). After describing Bach's other extant violin concertos, those in E major (BWV 1042) and A minor (BWV 1041), he adds: The Bach Gesellschaft published the concerto in 1874, edited by Wilhelm Rust. The Neue Bachgesellschaft reports around 25 known public performances of the concerto in the period from late 1904 to early 1907: most of these in Germany, but also performances in other European cities, including London, Madrid, Paris, Riga, St. Petersburg and Vienna, are mentioned.
