The tension generated by the half notes in the accompaniment at the beginning of the theme, and by the augmented second indirectly occurring between the first and third notes of the opening theme's melody, is likely a distinctive feature of the piece. These are resolved gradually in the latter half of the main section. In the trio in D-flat major, the melody shifts to the left hand, forming a long, arching phrase. Luptsova states that a waltz rhythm is employed in this trio as well, similar to the preceding piece.
