Rusalka is a Czech opera by Antonín Dvořák, composed in 1900.  The text was written by poet Jaroslav Kvapil (1868–1950), and is based on Czech fairy tales.  A Rusalka is a water sprite in Slavic mythology.  The opera was first performed in Prague in 1901, and quickly became a huge success.  The most popular aria is "Song to the Moon" in Act I:

I am here, waiting
If a human soul should dream of me
May he still remember me on waking
Dear moon, oh, shine for him…
