As we know, Chopin composed 4 impromptus, Impromptu No. 1, A flat major, Op. 29, Impromptu No. 2, F sharp major, Op. 36, Impromptu No.3, G flat major, Op. 51, Impromptu Fantaisie-Impromptu, C sharp minor, Op. 66. But, for the "Impromptu Fantaisie-Impromptu, C sharp minor, Op. 66 ". I have seen somewhere they wrote " Impromptu No. 4, C sharp minor, Op. 66, everyone please tell me that is correct or in correct? :cry:
Impromptu in C# minor or "Fantaisie-impromptu" was numbered the fourth, but actually the first one to be composed. Chopin composed it in 1834 but didn't publish it. It was until after his death that Chopin's friend Julian Fontana published it in 1855 and added "Fantaisie" into its title. According to music critic James Huneker, the title "Fantaisie" seems to be superfluous since this impromptu shares the same characteristics as other three. We cannot say that Chopin composed three impromtus and one fantaisie-impromptu as if the fantaisie-impromptu is something totally unrelated to other three impromtus. The conventional numbering method for Chopin's work follows the opus order. We have Impromptus Op.29, 36, 51, and 66. Numbers 1,2,3,4 are not official. The same reasoning follows for the Polonaise-fantaisie Op.61. It's a polonaise, hands down!
