The goal of this program is to compare the most prolific and important composers for lute, Johann Sebastian Bach and Sylvius Leopold Weiss. Bach met Weiss around 1740 and in that is when he wrote 6 suites for lute. Those suites are considerate one of the most difficult once for all lute repertoire. Johann Friedrich Reichardt describes: "Anyone who knows how difficult it is to play harmonic modulations and good counterpoint on the lute will be surprised and full of disbelief to hear from eyewitnesses that Weiss, the great lutenist, challenged J. S. Bach, the great harpsichordist and organist, at playing fantasies and fugues." The most imporant facts are that Weiss recommended Philipp Emanuel Bach in 1738 to Frederick the Great the King of Prussia and that J.S. Bach entirely copied Weiss’s Sonata SW47and arranged it for harpsichord and violin. American musicologist Douglas Alton Smith claims that Sylvius Leopold Weiss should be appreciated as are G.P. Telemann, F. Couperin, D. Scarlatti or other most important German composers in late baroque era. The program collect all kinds of musical genres: suite, sonata, prelude and chaconne.
