In Chopin's Waltz in C sharp minor, I'm a bit confused by the following notation:
The F has a natural, cancelling out the sharp in the key signature. But then it instantly becomes an F-sharp again. Once more there is no note to play for the accidental, so I don't understand what this piece of notation is telling me.
I would guess I play the F natural and then the G, then the next F in the bar I play as an F-sharp?
Thank you.
