Filiation of the sources
Principles behind the main text of
the Sonata in B flat minor Op. 35, I mvt
We accept as our basis FE4 as the last authentic source, compared to GC for the purpose of eliminating accidental changes and oversights by the engraver. In addition, we take into consideration the changes enriching the FE version and introduced by Chopin in GC and the basis for EE (e.g. more accurate, in general, dynamic markings), as well as the composer's alterations in pupils' copies.
