Bach's two-part Inventions and three-part Sinfonias are among the most important repertoire for early years development of keyboard technique. It is likely that Bach himself used these pieces as teaching material, and they prepare the way for the much more complex counterpoint of The Well-Tempered Clavier.

This Edition Peters Urtext edition containing the complete Inventions and Sinfonias, prepared by leading Bach scholar Ulrich Bartels, is based on Bach's autograph and has also been compared against the Neue Bach Ausgabe. In some of the pieces, the composer himself added additional ornaments at a later stage but did not otherwise undertake significant alterations. In every respect, this new edition of the collection therefore represents an authoritative musical text, without amendments or additions deriving from contemporary secondary sources.
