Leichtentritt believes that in fast tempo the sforzati climaxes in bars 16–45 can be perceived as a coherent contour line. Again, as in Op. 10, No. 1, Chopin achieves powerful sound effects with arpeggios in tenths on diminished seventh chords. After the climax, , "con forza" (45–47), a more transparent bridge leads to the return of the A section which recapitulates the first two eight-bar periods extending the cadence by four extra bars, increasing to and preparing the raging coda, "con più fuoco possibile" (as fierily as possible).
