Chopin seems at his most romantic in the Nocturnes; with the mazurk they belong to that group of works of the master, which is also accessible to the less experienced player. Both may explain the continued great popularity of these musically nuanced pieces. Like all Chopin publications edited by Jan Ekier, the soloist, educator and scientist within the Wiener Urtext Edition, the present edition also contains a rich commentary. In addition, comments on interpretation, regarding authentic variant, a characteristic of Chopin, are also included. They are most abundant in the famous E flat major Nocturne (Op 9, No. 2), which therefore appears twice in our edition: in the second reprint the variations are reproduced in their entirety; In an impressive way, they point to the improvisational moment of Chopin's art. The edition contains the 18 Nocturnes of Opus. 9, 15, 27, 32, 37, 48, 55 and 62, as well as three from the estate: the very early Nocturne in E minor, Nocturne in C minor (presumably from Chopin's final year) and the Lento con gran espressione (Nocturne in C sharp minor), in which Chopin quotes from other works.
