b. 29

composition: Op. 28 No. 16, Prelude in B♭ minor

..

In A (→FC,FE) there is no accidental before the 2nd semiquaver in the last group. The patent mistake, probably caused by the corrections to the figuration in the 2nd half of the bar, was rectified in GE and EE.

3   pairs in A

4 pairs in FC (→GE)

No markings in FE1

3 pairs in FE2 (→EE)

..

In FC (→GE), Fontana wrote one pair of signs ( ) more than in A – most probably a mistake. The absence of pedalling in FE1 is undoubtedly an oversight by the engraver. The markings were added in FE2 (→EE), however, the notation of A was not exactly reproduced.
