Crotchet e1 in A & IE

The addition of an augmentation dot to e1 is a wrong revision, based on the assumption that the bottom voice, represented by the e1 crotchet and the c1 quaver, should be complemented so that it is a minim. According to us, it is already complemented by the f1 quaver on which both bottom voices meet. An approximate record of voices performed by one hand is typical of the Chopinesque notation. In this case, it seems that it was the overly precise notation on the last quaver that caused the misunderstanding – had Chopin written the 2nd half of the bar as follows: , the mistake probably would not have happened.
The omission of this dot in IE, unless it is an oversight, proves that the engraver/reviser of this edition had a better understanding of voice leading.
