baby's music box

The primary purpose of a music box is to play sweet melodies that can attract and enchant the newborns; the sweetest and most relaxing melodies are particularly suitable for falling them asleep.
Another tranquilizing element is the repeated and regular rotating movement.
For this kind of music box the melodies are chosen very carefully: lullaby to fell them asleep, minuets to enchant them and marches to entertain them.
