A sharp erroneously placed in GE1 before g
1 was substituted in GE1a (→GE2) by 
confirming b1 in this chord. It was probably an engraver's mistake while moving before the middle note of the chord which seems natural in this context. The reviser of GE3 "corrected" this unnaturally sounding chord, by changing its topmost note, although in this case too, one cannot exclude the engraver's error. The erroneous accidental was not corrected until GE4 (→GE5). The missing in EE2 is clearly an oversight, corrected in EE3 (→EE4). The only correct version is the concurrent text of AI and FE.
