Bach's set of six sonatas for violin and obbligato harpsichord were written in Kothen between 1720 and 1723. Unlike most baroque sonatas, the keyboard parts to these sonatas were written out by Bach himself, not just left as figured bass. This second sonata is particularly noted for its third movement, in which the violin and keyboard play in canon.
