b. 1

composition: Op. 25 No 7, Etude in C♯ minor

Metronome marking with time signature in GC (→GE)

Metronome marking at start of Etude in FE & EE

..

Placing the metronome indication already at the beginning of the Etude may be a result of the routine interpretation of the engravers of FE and EE who did not see a reason to separate it from the Lento indication. Cf. the Etude in A minor, No. 11, bars 1-5.

b. 18-19

composition: Op. 25 No 7, Etude in C♯ minor

No indications in GC (→GE) & EE

ten. in FE

..

The authenticity of the ten. indications does not raise any doubts here. Chopin added them in the proofreading of FE or – which is more likely – still in the handwritten base text to this edition. The second possibility is backed by the presence of such indications in analogous bar 43 and similar bars 60-61, also in other sources – in bar 43 in GC, while in bars 60-61 in EE. Chopin could have added them subsequently in various manuscripts, however, he did not pay attention to synchronising the additions.

No marking in EE1 (→EE2)

..

The absence of  in both first impressions of EE suggests that it was also absent in the base text to this edition. The addition in EE3 was introduced – as many others in the entire Op. 25 – probably on the basis of GE.
