What changed in this conversion
- Some held notes in bars 42, 44–45, 49–50, 52–53, 64–65, 76–77, 137 are shown shorter because that hand plays more than one rhythm at once. No notes were removed.
- Some very quick notes in bar 49 were too close together to write separately, so they are shown as a chord. No notes were removed.
