       Two new Bach pieces just dropped!   Here is their world premier!   🎶 They are probably by the teenage Bach.  They were preserved in only one source.   The writer of this source was identified by the Bach scholar Peter Wollny as Salomon Günther John, a student of Bach in Arnstadt.  In 1727,  Günther John stated in an application in Schleiz that he had received his training “from the former organist in Arnstadt” and had subsequently worked “in the Grand Ducal Chapel in Weimar”.  John probably copied his teacher's early work during his time in Arnstadt as his student.This one is the Chaconne and Fugue in D minor (BWV 1178):https://www.youtube.com/watch?v=0X1xnYrP3Eo(1/2)

       This one is the Chaconne in G minor (BWV 1179).These world premiers were played by Ton Koopman.   According to the New York Times:"In 1992 Peter Wollny, then a Harvard graduate student in musicology, was researching his dissertation at the Royal Library of Belgium when he came across two unsigned music manuscripts so strikingly original that he had copies made and set them aside.“This is actually how I work,” Wollny said Tuesday. “Whenever I find something that poses a scholarly problem to me, I keep it. Even if it takes three decades, I don’t put it aside.”Wollny began to develop a hunch about who wrote these two anonymous, undated works for organ: Johann Sebastian Bach. But finding evidence required years of musical detective work, and it was not until this week, 33 years after the random discovery he made while doing research on one of Bach’s sons, that he officially announced the discovery."(2/2) https://www.youtube.com/watch?v=8gVG-wMwdsY
