When you twist the little crank of this music box, the melody of the birthday song "Wie schön, dass du geboren bist" (How wonderful that you were born) will be played. This song is one of the few birthday songs in German and is therefore particularly well-known and popular. It was set to music and lyrics by Rolf Zuckowski, who has become particularly famous as a composer and author of children's songs.
The gentle melody sounds more powerful when you remove the little musical mechanism from its lovingly decorated box. Since the mechanism is mounted on a small wooden board, this music box unfolds its sound particularly well when it is pressed onto a large resonating body, such as a table, a chair or a Cajon.
