Johann Sebastian Bach’s Clavier-Übung II was published in 1735, containing two works written for performance on a two-manual harpsichord. In the publication, Bach contrasted a work in Italian style – a Concerto nach Italienischem Gusto (Concerto after the Italian taste, now known as the Italian Concerto), BWV 971, with a work in French style, a suite which he called Ouvertüre nach französischer Art (Overture in the French style, also known as the French Overture), BWV 831. The Chromatic Fantasia and Fugue in D minor, BWV 903, is a work for harpsichord that Bach probably composed during his time in Köthen from 1717 to 1723. The piece was already regarded as a unique masterpiece during his lifetime. The pieces are here performed on two instruments built by Bruce Kennedy.
