ABSTRACT
Th e success of the Partitas evidently led Bach to continue the series. During the 1730s and early 1740s he brought out three further volumes of “Keyboard Practice” (Clavierübung) while producing WTC2 and the fi rst draft of the Art of Fugue. Th ese years also saw the preparation of the harpsichord concertos and other ensemble works thought to have been for the Leipzig Collegium Musicum. Bach seems to have composed few new keyboard works apart from those included in the great collections. But he also composed or revised a few lute pieces that are more or less playable on keyboard instruments; two transcriptions (one fragmentary) for keyboard also probably date from this period.
