The original score was in a sorry state: the notes were carelessly marked, the lines were broken, and the paper was covered in smudges. I took the utmost care in reconstructing it: I erased the smudges, traced the lines with a ruler, blackened the bellies of the quarter notes, and added tails to the eighth and sixteenth notes. I believe that today's version of the work will stand up to even the most rigorous standards.
