Bach’s Penmanship: A nearly 300-year-old musical manuscript housed at the Carnegie Library in Pittsburgh contains what is believed to be the earliest examples of Johann Sebastian Bach’s handwriting, officials said Tuesday. The three-leaf manuscript is Bach’s copy of an organ prelude and fugue in G minor by the German composer Dietrich Buxtehude (1637-1707) that was given to the main Carnegie Library in 1895.
