In A major, in binary form.

The theme is bright, light, and cheerful, evoking the image of grape harvesting. In the first two measures of section 'a', the tonic note is sustained in the bass as a pedal point; while a vigorous, leaping quality is not felt, a cheerful atmosphere is created by the dotted rhythms, and a sense of lightness is conveyed by the avoidance of the low register. In section B, the left hand carries the melodic line. This melody eventually shifts to the right hand from measure 23, returning to the main theme.
