Op. 16, Rondo in E♭ major

The first German edition is based on FE and was not proofread by Chopin. The text was reproduced with a significant number of inaccuracies and oversights; at the same time, a number of revisions was introduced, mostly arbitrary (e.g. the length of accents was approached quite liberally). A relatively small number of mistakes was corrected:

• necessary accidentals were added in bars 173, 227, 271, 274, 326,
• cautionary accidentals were added, e.g. in bar 163,
• slurs were corrected and the overlooked ones added in bars 40, 230, 255, 289-290,
• a  mark was added in bar 282,
• the erroneous  in bar 305 was removed,
• the beam in bar 352 was corrected.

However, a number of new mistakes and inaccuracies was committed:

• the necessary accidentals lowering/raising notes in bars 19, 256, 302, 454 were overlooked,
• a b crotchet was printed instead of an a minim in bar 7,
• the accents in bars 31, 185-186 were overlooked,
• other articulation markings were overlooked – staccato dots and wedges – in bars 32, 57, 126, 131, 134, 304, 311, 368, 380, 384-385, 402, 460, 464,
• the meno mosso indication in bar 37 was misplaced,
• the crotchet stem in bar 439 was overlooked, in turn, an additional crotchet stem was printed next to the 5th semiquaver in bar 69,
• a note in bar 70 was overlooked,
• slurs in bars 92-93, 238, 337-338, 404, 443-444 were overlooked, and a motivic slur was placed instead of a tie in bars 429-430,
• the hairpins in bars 31, 93, 415, 449-450 were overlooked,
• dynamic markings were overlooked ( or ) in bars 408, 448 and cresc. in bar 33,
•   was printed instead of  in bars 13, 236,
• the fingering in bar 31 was overlooked,
• some of the pedalling marks in bars 83, 103, 105, 213, 360, 364, 384-385, 387, 392, 393, 403 were moved.

Many differences with respect to FE can be described as inaccuracies, which, however, often resulted most probably from a routine approach to certain rules or notation conventions rather than from carelessness:

• a liberal approach to the length of accents or hairpins, particularly changes of long accents to short ones,
• omission of dashes marking the range of dynamic changes (cresc. or dim.),
• replacing all wedges with staccato dots,
• inaccurate slurring – moving the beginnings or endings of slurs.
