Johann Sebastian Bach was not only an extremely skilled composer, but also an ingenious teacher. Today, many piano students learn the basics of technique with his InventionsŒî and SinfoniasŒî and at the same time themost important elements of classicalŒî music. Bach called the 15 two-pa rt pieces InventionsŒî and the three-part ones SinfoniasŒî. He wrote a preface to the musical text, dedicating it to amateurs of the piano, butin particular to those who desire to learnŒî. Bachs preface and a table with the most common ornaments in the Clavierb_chlein f_r Wilhelm Frie demann BachŒî are also reproduced in this Henle edition.
