Bach Concerto D minor BWV 1043 for 2 Violins and Orchestra (Henle)

Wilhelm Friedemann Bach was a highly talented German composer and performer born in 1710. He composed Three Duets for Two Violas in Berlin around 1775, which inherited the contrapuntal style of his father and contributed significantly to Berlin's musical heritage. There is a cyclical connection among the duets, and Bach adapted the music to maintain harmonic and melodic balance between the two instruments.
