C-sharp major
The second section is the "friska". It opens quietly in the key of F-sharp minor, but on its dominant chord, C-sharp major, recalling a theme from the lassan. The alternating dominant and tonic harmonies quickly increase in volume, the tempo gaining momentum as the Friska's main theme (in F-sharp major) is approached. At this point, the Friska begins its journey of ever-increasing energy and pianistic bravura, still underpinned by alternating tonic and dominant harmonies. Modulations are limited almost exclusively to the dominant (C-sharp major) and the lowered mediant (A major). Before the final whirlwind of sound, a moment of calm prevails in the key of F-sharp minor, recalling another of the lassan's themes, and is followed by the instruction, Cadenza ad lib. Finally, in the key of F-sharp major, there is a crescendo of prestissimo octaves, which ascend and then descend to cover almost the entire range of the keyboard and bringing the Rhapsody to a conclusion.
