The Toccata is an exuberant, energy-filled extravaganza with many deceptive cadences at the end. The relatively little-known double fugue is enjoyable in its own right, however. The first subject is chromatic and the ornaments are preserved throughout. The second subject enters on the Swell and is a jumpy little thing. When the first theme reënters in the alto, though, Bach surprises us by following it with a pedal entrance of the second theme. Impulse reverberation added. [13:6]
