Chopin's Mazurka in F minor uses many chromatic harmonic techniques. For example, in measures 10-13, the is a chromatic falling fifths pattern, going from G to Gb to C to Cb. Also, in measure 29, a German 6 chord is reinterpreted enharmonically as a V7 chord. In measures 24-29 there is a modulation to a chromatic-mediant related key. Finally, in measures 11-14, there are chromatic passing tones embellishing the opening melody.
Sorry this is crappy, I have 5 billion more things to get done.
