Bach's Inventions and Sinfonias are rightly considered as indispensable to every pianist. in his famous preface to the collection, Bach himself called it an ''Instruction'' which teaches students and keyboard lovers to ''treat correctly'' both two and three voices, to ''achieve a singing style in playing'' and to ''acquire a strong foretaste of composition''. To this end, Bach created timelessly beautiful music which has lost nothing of its relevance to us nearly 300 years after its creation. Henle now presents a new edition of this classic collection, which draws upon all known sources and offers the best in ''instruction'', especially with respect to the transmitted embellishment variants.
