b. 2

composition: Op. 28 No. 8, Prelude in F♯ minor

..

In A (→FC) b. 2 is marked with / signs as a repetition of b. 1. This raises doubts about whether and which performance indications are to be included in b. 2 (except for the tempo/character marking, of course) – FE (→EE) repeated pedalling markings and slurs, but omitted accents.

2 slurs in A (→FEEE) & CGS

Continuous slur in FC (→GE)

..

Fontana's mistake in the interpretation of the slurs of A could have been caused by a slur from the next page of A clearly showing through the paper – a fragment of a slur of the Prelude in C Minor seems to combine the two slurs of A in this place.

c in A (→FCGE1, →FEEE) & CGS

d in $GE2 (→GE3)

The version of GE2 is a result of an arbitrary revision, provoked by a mistake committed in GE1 in the next triplet, i.e. a c was printed there instead of a d, which is a patent mistake. While correcting that place the reviser of GE2 probably started thinking that the middle notes of the triplets are to create an octave echo of the melodic notes in this entire fragment (b. 1-3 corresponding in GE to the first line of the text) and changed c to d also in the 2nd triplet. Consequently, none of the impressions of GE includes the correct text in this bar.

b. 2

composition: Op. 28 No. 10, Prelude in C♯ minor

..

In FE1 the 4th and 5th semiquavers of the bar are b1-a1. It must be a mistake – it is likely that the engraver was influenced by the structure of the previous and the next two figures. The error was rectified in FE2; it is also all the remaining sources that include the correct version, analogous to b. 6 and 14.

b. 2-8

composition: Op. 28 No. 24, Prelude in D minor

..

In A (→FC) the L.H. part is marked in these bars (as well as in b. 9) in an abridged manner as repetition of b. 1.
