How accurate is this score?The notes were typed in from photographs of one edition (Henle), and drawn by computer. Every page was transcribed twice, independently, and every disagreement was settled against the photograph (zoomed in, and the position of each disputed note head measured against the staff lines). The facts below about keys, bars, repeats and returns of music were found by searching the typed notes. As a check, the same music was typed from two different pages (bars 12 to 25 and bars 54 to 67) and comes out almost the same. Not exact: ornaments (the turns in bars 56 and 57 carry a natural sign that cannot be typed), the small grace notes, and some slurs may differ in detail from the print. Not typed in: fingering, most dynamics, and the editorial brackets. If anything here disagrees with your own score, your score is right.
About bar numbersThe numbers under each line are the ones printed in the Henle edition (the small number above the first bar of each line). Another edition may number differently, so in the exam point to the music, or name the edition, before you say a number.
