All piano students are familiar with Bach's two-part Inventions - but virtuosos of the keyboard also keep coming back to these timelessly beautiful but by no means easy works. It is hard to believe what Bach was able to expressing only two parts! In his famous preface the composer himself calls the work an Instruction which teaches students and keyboard lovers to treat correctly several parts, to achieve a singing style in playing and to acquire a strong foretaste of composition. Henle now presents a new edition of this classic collection, which draws upon all known sources.
