listen to the newly discovered composition by J.S. Bach

Michael Maul, a classical music scholar and a researcher for the Leipzig Bach Archive has discovered a composition by Johann Sebastian Bach. He found the score two weeks ago among documents from the Anna Amalia Library in Weimar. The two-page aria was dated October 1713 and the piece is for soprano, strings, and basso continuo in honor of the 52nd birthday of Wilhelm Ernst, duke of Saxe-Weimar, whom Bach served as court organist.

I've heard an excerpt of it and it sounds lovely. Listen to the excerpt from NPR here.
