b. 49

composition: Op. 27 No 2, Nocturne in D♭ major

D flat in A (→GEFEEE)

An octave sign written into FED

..

The sense and authenticity of this sign in FED is doubtless, yet due to the much more powerful and longer-sounding bass register of contemporary pianos this variant may only be used with utmost caution.

b. 59-60

composition: Op. 27 No 2, Nocturne in D♭ major

No octaves in  A (→GEFEEE)

Two octaves in FED and FEJ

Three octaves in FES

The editors' variant proposal

..

In the three teaching copies, the bass notes in  bar 59 were doubled with lower octaves. In FES the octave progression is consistently brought to the beginning of bar 60. In our opinion this means that Chopin considered the version with the octaves at least equivalent to the version of A (→GEFEEE), in which single notes appear.
