The world-famous pianist András Schiff, a most familiar name to Bach fans on account of his complete recordings of Bachs piano works, has provided fingerings for both parts of the Well-Tempered Clavier. He discusses aspects of performance practice in a detailed preface. The basis for the musical text was Henle's revised edition of Part I published in 1997 and Yo Tomitas brand new revision of Part II (spring 2007). The eminent Bach scholar Tomita discusses the complicated source situation of Part II in an extensive preface. A detailed commentary rounds off the edition.
