Accents between or above notes in FC

Accents above notes in EE & GE

Accents above notes or pairs of accents in FE

Pairs of accents suggested by the editors

In these bars Chopin was also looking for a deft way of marking the accents referring simultaneously to the parts of both hands (cf. bars 29-32 and 41-44). In the main text, in both texts we adopt pairs of accents used in FE – most probably by Chopin – in the 2nd half of bar 46.

In the main text we give the hairpins on the basis of #GC, in which the range of the sign is compatible with the natural course of the music. The slightly longer hairpins of EE are probably authentic too. In turn, the sign of FE could have been shortened or moved due to the lack of possibility of its legible placement on the 2nd beat of the bar.
