Impromptu No. 2 (Chopin)
Frédéric Chopin's Impromptu No. 2 in F♯ major, Op. 36 was composed in 1839 and published in the following year.
Music
The Impromptu begins with a nocturne-esque chord. The piece is in the less commonly used key of F♯ major, which is used in very few major compositions in the Romantic era, such as Ludwig van Beethoven's Piano Sonata No. 24 and Chopin's famous Barcarolle.
gollark: With reals it's n or less which is bad and nobody likes it.
gollark: It means that for a polynomial P(x) with degree n, P(x) = 0 has exactly n solutions.
gollark: … no.
gollark: Oh, and I should mention that the fundamental theorem of algebra is only for polynomials with a single variable in them, not stuff like x³y² which contain several.
gollark: i.e. you can get some twice or more.
