It utilizes the "Polska" rhythm, a Scandinavian folk dance. It can be described as a cheerful folk dance celebrating the summer solstice in Northern Europe. It has a simple structure: theme, development section, Gammal rundans (old-style round dance), and recapitulation.

The theme is clear and cheerful. The stable bass line is solid and rich. The melody, employing dotted rhythms, has an extremely bright flow of sound.

The development section is lively and dance-like in its depiction. From measure 15, the melody dances like a round dance. The low register sustains a G note. The inner voices ascend chromatically, creating a sense of exhilaration. It evokes the bonfires lit during the Midsummer festival. In measures 17-18, it modulates to D major.

From measure 19 to 28, it is expressed as a Gammal ringdans. It rushes as if drawing an arc. The indication "quasi Clarinetto" requests the sound of a woodwind instrument. The left hand also gently ascends and descends in eighth notes, singing broadly.

From measure 29, the recapitulation begins. It modulates to G major, and the Polska reappears. The coda is powerful, with repeated chords, concluding grandly with fz.
