It is almost impossible to tell from listening to them that Bach´s extremely popular concerti for harpsichord were probably his own transcriptions of solo concerti which had originally been composed for violin or a woodwind instrument. The outer movements of the second concerto, in E major, probably written around 1738, sparkle with joy, while the expressive melodic lines of the middle movement, the Siciliano in C-sharp minor, transport the listener to the realm of his Passion music.
