b. 66-70

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

..

In A (→FE,FCGE), both in b. 66 and 70, there is no  before the 14th note of the roulade (b1). Taking into account the fact that the note was initially preceded by a b2 note written at the same pitch (under an octave sign), we do not consider it a mistake. In the main text we add the accidental; it is also in EE.

Octave in A (→FEEE)

The absence of the lower note of the octave is undoubtedly an error by Fontana in FC (→GE).

b. 72

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

..

The 4th semiquaver in the 2nd half of the bar in GE is an erroneous F note instead of D, which is in the remaining sources (in the manuscripts the 2nd figure is marked in an abridged manner as repetition of the first).
