Bach's 15 two-part Inventions and the 15 three-part Sinfonias played an important role in Bach's teaching. These pieces, although today mainly associated with basic keyboard training, are not at all easy and in fact are sophisticated, small-scale masterpieces. They were not composed simply to provide technical training in keyboard playing but, perhaps more important, to teach keyboard players how to compose. In 1720, Bach's oldest son Wilhelm Friedemann (1710-84) was already of an age appropriate for introducing him into the family trade of musician. So Bach started for him a music notebook: a Clavierb�chlein which included these Inventions and Sinfonias. In learning and playing these works, Bach affirmed, a diligent student would be taught "a clear manner for playing not only in two voices but also in three obbligato parts and, furthermore, not only how to invent good musical ideas [inventiones] but also how to develop these well. And above all, how to achieve a cantabile manner of playing, and additionally to obtain a strong foretaste of Composition. " Wolfgang R�bsam is internationally known as an authoritative Bach interpreter, from recordings of the organ and harpsichord on several different labels. This new recording is played on a lute-harpsichord, an instrument that Bach would have had at home for both music-making in the family and for teaching. The touch required and the sonority produced is delicate, subtly shaded, and closely related in it's effect to the music of Bach's French contemporaries, whose music he knew well, such as Fran�ois Couperin, Jean-Philippe Rameau, and Louis Marchand. The sound is warmer, as it has gut strings and no dampers. "These lovely performances memorably showcase R�bsam's sensitive and poetic side. Recommended. Performance: 9," wrote Jed Distler of ClassicsToday. Com about the earlier issue of R�bsam's recording of Bach's French Suites (BC 96227).
