Johann Sebastian Bach ： Well-Tempered Clavier II no.10 e-moll BWV 879

The tenth pair in Book II of the Well-Tempered Clavier consists of a prelude and a fugue. In the prelude, it is important to maintain the flow while listening for the movement of each voice, giving even the succession of shorter notes a natural sense of direction. The fugue is especially rewarding for the way its subject passes between voices and the independent lines combine to create tension. The performer should treat the voices with equal care while clearly bringing out each entrance of the subject. Avoid rushing the ornaments and smaller figures, and use secure fingering to shape a transparent sonority that allows the contrapuntal character to emerge.
