b. 69

composition: Op. 2, Variations, complete

Ee in AsI & A (→GE1FE,EE)

E & e in GE2 (→GE3,FESB)

..

The version of GE2 (→GE3,FESB) with E and e in the 2nd half of the bar is almost certainly an arbitrary revision, introduced probably by analogy with b. 65. The version is contrary not only to AsI and A (→GE1FE,EE), but also to the Mozartian original. Cf. also two respective fragments of the 2nd variation and the finale (b. 141 and 280-281).
