In Bach's 48 Preludes and Fugues (known as The Well Tempered Clavier), most of the fugues consist of three or four parts and sometimes more. This particular fugue is the only one in the collection with just 2 parts or "voices", yet it still requires some practice to play it well. The fugue (and its corresponding prelude) are in the key of E minor and together the pair are catalogued as BWV 855 of Bach's works.
Although there are some easier preludes and fugues in the set, much of Bach's Well-Tempered Clavier is quite challenging to play. However the complete set has for a long time been considered a must for any serious student of piano. Some other preludes and fugues from the set are available on mfiles if you check the Bach page or Classical Sheet Music page. If you have aspirations to be a good classical pianist then we recommend getting the complete Well-Tempered Clavier which comes in two books. Here are links on "sheet music plus" to Book 1 and Book 2 of the Well-Tempered Clavier.
