I just purchased an edition of Chopin's Nocturnes entitled: "Chopin Complete Works VII Nocturnes. Edited by Ignacy Paderewski". Originally published in 1949 by the Instytut Fryderyka Chopin in Warsaw, Poland, this is evidently a very serious attempt at reproducing Chopin as faithfully as possible, using original manuscripts and notes whenever possible.
Each nocturne is discussed separately at the end of the book, with measure-by-measure evaluations of how the various sources were analyzed and interpreted.
One example, from a discussion of Nocturne in B major, op. 62 no. 1: Bar 6: In [the original German edition, (Breitkopf & Hartel, Leipzig, No. 7547)], there are not four equal quavers in the top voice at the beginning of the bar, but only two quavers, a dotted qaver and a semiquaver. The same applies to the second half of bar 31.
There are over 15 pages of this stuff. Its interesting to compare this edition to those available for free or a price from various internet sources.
Just wondering if anyone else out there has had experience with other editions of Chopin's works edited by Paderewski and his group?
