b. 20
The fourth semiquaver in the R.H. in A is written too low, so it resembles rather a d1 than an e1. This is how it was interpreted in GE1 (→GE1a). The erroneous d1 is also present in CDP and EE, while the visible traces in FE prove that initially also this edition included d1. It constitutes a strong argument for – indirect or direct – provenience of all these sources from A. Apart from AI and FE, the correct text is also to be found in GE2 (→GE3).
