The main key is F major, and it is in binary form.

• A [a (measures 1-8) + a1 (measures 9-16)]
• B [b (measures 17-24) + a1 (measures 25-32)]
• B [b (measures 33-42) + a1 (measures 43-48)]

Although there are three large sections, since the third section is a repetition of section B, it is essentially a binary form of A+B.

The opening of the theme ascends from an arpeggiated line of the tonic chord, as if stretching upwards, and over four measures, the harmonic tension of I→IV→I becomes a gentle subdominant progression. Overall, broad melodic movement is dominant, truly evoking the work's title.

In section B, the melodic line shifts to the left hand and modulates to C major. The transition between sections, without a significant change in atmosphere despite the shift, likely expresses the refreshing morning atmosphere, as suggested by the work's title.
