b. 33-34

composition: Op. 10 No 1, Etude in C major

Tied B in CLI

Tied octave (original version)

B1 & octave in FE (→GE,EE

..

CLI has a sustained B as a bass note in these bars. This is the original version, moreover, it was almost certainly written with an error – same as in the adjacent bars, it was the B1-B octave that was supposed to be in this place (cf. e.g. bars 3 or 23-24).

The dynamic indications in bars 33 and 36 constitute a part of frugal, yet undoubtedly authentic performance indications of FE (→GE,EE).

Ties in FE (→GE,EE)

In CLI the lack of hold of the bass octave is most probably the copyist's error.

Our suggestion

..

In FE (→GE,EE) the  indication seems to be valid only from the semiquavers in the R.H. According to us, it is however highly unlikely for this indication not to include also the long resounding octave in the L.H. Therefore, we consider it as the notation's inaccuracy and in the main text we propose a relevant minor correction of the sign's placement. See also bar 45

Slurs in FED (interpretation)

..

In FED the added not entirely clear signs may be interpreted as slurs, e.g., reminding of the legato articulation or underlining the dynamic change and beginning of the new phrase in bar 37.
