Bach's set of six sonatas for violin and obbligato harpsichord were written 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. In this first sonata, Bach often mirrors the violin part in the keyboard, particularly in the 1st and 3rd movements.
