Pas de Deux is a short, romantic encounter between two characters. The piece begins with the bass stating a pursuit motif which is rebuffed by the flute. The bass briefly laments, but when its song is ignored it leads to a quarrel. The bass "clears the air" with a pizzicato/arco combination in double stops. The flute plays a conciliatory theme to which the bass responds warmly. They restate their romantic lines, accompanying each other in turn. The high point is a divergence in opposite directions to sustained D flats, played fortissimo. During its cadenza, the bass abruptly recalls the pursuit motif. The flute continues to play "hard to get", but hesitates when the bass retreats. Finally, they forgive their differences, uniting in a final restatement of the flute theme.
