The Kingdom (Elgar)
A lot of the music is calm and thoughtful rather than dramatic.  If Elgar had completed all three oratorios, The Kingdom  would have been the middle one: quiet and relective between two more dramatic ones.  As in The Apostles , Elgar used the idea of the Leitmotif.  This is something that Richard Wagner had developed in his operas: the technique of having short tunes (motifs) which represent particular characters or events in the story.
