The sources differ here with regard to the placement and scope of hairpins 
in bars 1-2, 3-4, 9-10 and 11-12. The differences in the scope only relate to the starting points; in bar 1 of GC and bars 1, 3 and 9 of FE the hairpins begin on the 2nd note. We consider it to be an inaccuracy of notation. In FE and GE the hairpins are placed horizontally between the staves. GC has a similar arrangement, although the signs in bars 9-12 are written onto the lower staff, which cannot be reproduced in print For our main text we adopt the graphic layout of EE, wich may correspond to the notation of the autograph.
