Among the numerous manuscripts from C.P.E. Bach in the library only a small handful have been identified as autographs. Most of these are from the Wagener collection. One extraordinary item was identified by the German musicologist Peter Wolny as an autograph keyboard sonata by C.P.E. Bach but the title on the cover is in the handwriting of Johann Sebastian Bach! It is exciting indeed to think that this manuscript passed through both of these masters’ hands (see images above).
