I was comparing the Polonaise Op. 41 no. 1 Henle Urtext edition with the Schirmer Mikuli edition, and found some startling differences. Allow me to list some examples: In measure 3, the last right hand chord according to Henle is C#-A-D, but in the Schirmer it is D-A-D. In measure 31 of the Henle, the first right hand chord is C#-G-A-#C, where is it C#-G-C# in the Schirmer. In measure 37 according to Henle, the first note is an A octace in the right hand, and followed by F-C-F in the left hand. In the schirmer edition, that A octave has an Eb and the left hand also contains en Eb. (The same situation applies for measure 38.) My first thought was to play it as the Henle suggests, since Mikuli might of changed some notes around. Is the Henle the best and most accurate version to trust? Are those aforementioned measures correct in the Henle? I learned this piece a while back using the Schirmer, but now the Henle editon makes me want to make some changes, since it seems more definative.
