Says The New Grove: "....Several biographers have told the story of how [Johann Sebastian's older brother] Christoph would not allow his brother to use a certain manuscript; how Sebastian copied it by moonlight; how Christoph took the copy away from him; and how he did not recover it until Christoph died.....Later authors, knowing that Christoph lived on until 1721, and that the brothers had been on good terms, have tended to reject the story--perhaps unnecessarily, for it may illustrate contemporary attitudes to discipline and restraint. In fact, the story fits in well with the little that is known of the Ohrdruf years, and with the idea that Sebastian taught himself composition by copying. Most probably he recovered his copy when he went to Lueneburg. As for its contents, Forkel implied that it contained works by seven named composers, three of them northerners. He probably misunderstood Emmanuel's reply to another of his questions; according to the obituary, the manuscript was exclusively southern (Froberger, Kerll, Pachelbel)--as one would expect since Johann Christoph had been a Pachelbel pupil...."
