Johann Sebastian Bach : Fugue No. 10 from book 1

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 only 2 parts, yet it still requires some practice to play it well. These pieces are considered to be standard repertoire for serious piano students. The complete collection of Book 1 and Book 2 are available from Sheet Music Plus.
