The prelude is built out of a few themes which are associated with some of the most significant elements of the play.  Not one of them is a personal label, as is widely, but erroneously, supposed to be the case in Wagner’s dramas.  They stand for dramatic ideas and agencies, and when these are passed in review, as it is purposed shall be done presently, it will be found that not the sinister but the amiable features of the story have been chosen for celebration in the overture.  Here, too, in what may be called the ethical meaning of the prelude, Humperdinck has followed the example of Wagner in the prelude to his comedy.  Simply for the sake of identification hereafter names will be attached to the themes out of which the prelude is constructed and which come from the chief melodic factors of the opera.  The most important of these is the melody sung by the horns at the beginning:—­

Let it be called the “Prayer Theme,” for the melody is that of the prayer which the little ones utter before laying themselves down to sleep in the wood.  The melody seems to be associated throughout the opera with the idea of divine guardianship, and is first heard in the first scene, when Hansel, having complained of hunger, Gretel gently chides him and holds out comfort in the words (here I use the English version of the opera):—­

  When past bearing is our grief
  God, the Lord, will send relief.

Humperdinck’s splendid contrapuntal skill shows itself in a most varied use of this theme.  Once in the prelude it appears in three different forms simultaneously, and in an augmented shape it forms the substratum of the prelude, while other themes are cunningly woven above it.  The second theme is an exceedingly bright and energetic little phrase with which the rapid portion of the prelude begins.  It shall be called the “Counter-Charm” theme, because it is the melodic phrase which serves as a formula with which the spell which the witch puts upon her victims is released by her as well as by the children who overhear it.  When it occurs in the play it has this form:—­

Words and music come from the mouth of Gretel when she releases Hansel from the spell in the third act, and from that of Hansel when he performs the same office for the gingerbread children.  After two phrases of minor significance there comes the “Theme of Fulfilment,” so called because of its association with the answer to the prayer for protection in the woods.  Thus it forms part of the dawn music at the beginning of the third act when the children are awakened by the Dewman.  It makes up the original part of the song of this Dawn Fairy and is the melody to which Hansel and Gretel sing their explanation to the wondering gingerbread children:—­

  The angels whispered in dreams to us in silent night
  What this happy day has brought to light.
