The interpretation of contrapuntal music makes particular demands on the pianist. Book 1 begins with easier pieces from the repertoire (ostinato forms, canons, pieces with walking bass) and takes us through easy dance movements up to the Inventions by J.S. Bach. The pieces are grouped systematically, to distinguish three ways in which parts are distributed: Two Parts in the right hand, one in the left • Two Parts in the left hand, one in the right • Examples in which the middle part is divided between the hands.
