Principles behind the main text of the
Polonaise in E flat minor Op. 26 No. 2
We base our text on FE2 (the last authentic source) compared with A in order to eliminate accidental changes and oversights by the engraver. We consider the improvements Chopin made when proof-reading FE in passages that repeat as binding on all repetitions, even if they have not – through oversight on the part of the engraver or of Chopin himself – actually been included everywhere. We also take into consideration annotations Chopin made in his pupils' copies.
