Bach’s Chromatic Fantasia and Fugue in D minor (BWV 903) was most likely composed during his tenure in Köthen, around 1717-1723. There are numerous surviving copies of this harpsichord work. It is believed that Bach continued to work on the piece even after he arrived in Leipzig.
The Fantasia is unique in all of Bach’s works. Its improvisatory and virtuosic style is a precursor to music of the Romantic period. Glenn Gould even referred to the work as “a monstrosity!”
