A movement of a Beethoven string quartet, written in the composer’s hand, is coming up for auction. Earlier this year a manuscript copy of Beethoven’s 9th Symphony sold for $3.47 million. “Unlike that manuscript, which was prepared by a copyist but had Beethoven’s corrections and comments on most of its pages, the quartet movement is entirely in Beethoven’s hand. Sotheby’s says it expects the manuscript to bring between $1.6 million and $2.5 million.”
