b. 15-16

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

2 half-bar long  in A (contextual interpretation→FEEE)

Different  in FC

Different  in GE

..

Both  marks in these bars have clearly different arms in A – the top arm begins in the middle of the bar, while the bottom one – on the 2nd beat. According to us, it is the top arm that should be regarded as reliable, since it was written first. This is how those marks were interpreted in FE (→EE) and the latter also in FC (inaccurately reproduced in GE). In FC (→GE) in b. 15 Fontana averaged the length of the arms.

a-g1 in GE

The notation of the chord on the 2nd quaver in the bar is ambiguous in FC – the c1 note, although most probably written by Fontana, is actually imperceptible and was not included in GE.
