Schumann paints this tender picture with a simple flowing phrase, to say that children from all over the world are the same, no matter where they reside. One perceives this as a short barcarolle, sailing through seas of distant lands. A singing melody, with a slightly softer rolling triplet support, helps to establish the sweet mood of the work. Play the left hand softly allowing the melody to sing effortlessly.
Perhaps Schumann reflects that Clara’s father had forbidden them from seeing each other. They see one another in the same city, and it pains them not to acknowledge the other’s existence. They are like foreigners from distant lands.
