Sunday in the Park opens with an accompanied cadenza for the soloist, which leads to a gentle rhythmic melody with a laid-back feel. This is taken up by the band but the soloist sparks a change of mood by introducing a faster light rock interlude. This reaches a climax, at which point the music unwinds until the original mood returns. A variation on the original melody leads to a short cadenza from the soloist, which brings the work to a peaceful close.
