In the finale of the play, the grown-up Aladdin replaces the lamp with its genie (or spirit) back in the magic cave where he first found it. The somewhat obscure (if exalted) words that Busoni sets are voiced by the rock pillars themselves: Oehlenschläger's stage direction ""Deep and quiet, the pillars of rock begin to sound:"" is printed above the score where the chorus enters. Busoni follows the text exactly, only omitting a few verses which were not appropriate. According to Dent: "The actual meaning of the words hardly matters. The chorus is directed to be invisible; it sings in plain chords, like a body of soft trombones added to the orchestra. The effect which Busoni desired was stated by him once in a letter to a friend who had mistakenly suggested to him that it might be better to re-write the chorus for mixed voices; he replied that he had no desire to convert his Concerto into an oratorio; he insisted that the chorus should be invisible, and said that its function was 'to add a new register to the sonorities which precede it'."
