composition: Op. 44, Polonaise in F♯ minor

As with other analogous places, in FE (→EE) the L.H. part octaves (from the 2nd beat of the bar to the end of the bar) are written in a simplified manner with the use of con 8va.

No ties in CLI

No ties in FE

Ties in GE & EE

..

In FE there are no ties sustaining the upper notes of the octaves in bars 73-74 and 75-76. According to us, the most probable explanation is a misunderstanding at the time of changing the original abbreviated notation of the octaves with the use of under the upper notes for regular notation. In CLI the octaves, written in the described brief manner, are not sustained at all, which most probably is a mistake.

Octaves in A

Single D in FE (→GE,EE)

..

It is uncertain whether the octaves, written in A in an abbreviated form with the use of 8, were not simply overlooked in FE (→GE,EE). Stylistically, both versions seem to be equal. In the main text we give the version of the editions, as Chopin could have considered it as the correct one even if it had emerged accidentally (there are no entries in this place in any of the pupils' copies).
