Waltz by chopin op?

[frigo]

I have hear a "waltz in C sharp minor" by chopin but it hasn't the opus number. I have a problem in my computer's audio functions that stop me from searching for it on the internet, because the only thing I have is the music on a cd that gives less information about pieces than it should.

Can someone tell me the opus? I give some clues: it is a very beautifull waltz that starts with some dissonant chords (I don't know if they are really dissonants, but they seem when listening) in the lower times that fall in a whirlpool of notes that finishes resting on a beatifull sequence of sharped notes.

Anyone knows?

 i would say that it's opus 64 number 2.

 anyway, try this link to hear a sample of each waltz:

 notice that there are other waltzes by him without opus number but i don't remember if any is in c-sharp minor.
