. In the recapitulation, the key for this passage is changed to bring the second subject back in A-flat major: the transitional passage appears in a key that would theoretically be F-flat major, but which is notated in E major, presumably because Beethoven judged this easier to read – this key being a major third below the key of the earlier appearance of this passage. Likewise, the second movement (in A-flat major) of Beethoven's Piano Sonata No. 8 (Pathétique) contains six measures of what would theoretically be F-flat major, but notated as E major (keeping the 4-flat key signature of the movement, so every note in the passage has an accidental). Another example of F-flat major being notated as E major can be found in the ''Adagio'' of
