After a short and graceful introduction, the cantata opens with a solo describing the quiet beauty of a summer night, daintily accompanied by wind instruments and harp. A second voice replies ("O Summer Night"), and then the two join in a very vigorous duet ("O fill thou Even with Light of Heaven"). A short solo for third voice leads up to a chorus which gives us a picture of King Trojan's castle gleaming in the moonlight. It is followed by a very effective solo for the King ("The Horse is neighing, O Page of mine"), in which he bids his Page saddle his steed for a night ride to visit his distant love. The chorus intervenes with a reflective number ("What thinks she now?"), which is very dramatic in style, describing the mutual longing of the lovers to be together.
The second scene opens with a short solo by the Page ("Up, up, O King, the Horses wait"), followed by the chorus as narrator, describing the ride of the King and his companion through the greenwood, with which is interwoven Trojan's solo ("How sweet and cool is yet the Night"). In the next number, a vivacious allegro, the story of the ride is continued by the chorus, with a characteristic accompaniment, and again Trojan sings a charming tribute to the summer night, which is followed by responsive solos of the King and the Page, in the allegro and penseroso style,--the one singing of the raptures of night, the other of the gladness of day and sunlight. A passionate bit of recitative ("Now swift, ye Horses") by Trojan reveals the secret of the King's haste. He is King of the night, and the morning ray will be fatal to him. A short choral number ("And forward fly they") brings the first part to a close with the arrival of the riders at the Queen's castle.
The second part opens with a beautiful solo, quartet, and chorus ("Good-Night, the Lindens whisper"), which describes the meeting of the lovers, while
"Beneath the lofty castle gate Slumbers the page who so long must wait. Then crows the cock, the hour is late."
At this note of warning the Page appeals to his master to fly, for the sunlight will bring him pain and harm. The dallying King replies, "Hark! how the Nightingale yet sings." A small chorus intervenes with the warning, "Love is so fleeting, Night is so fair." The Queen appeals to him, "What seest thou, O King?" To which Trojan replies with agitation, "The ruddy Morning, it is my Death." Again comes the Page's warning. The King springs up in alarm and hastens to his steed. In a choral presto movement the ride back is described. The King conceals himself in a dark thicket, hoping to escape, but the night has vanished and the day has begun. Its beams penetrate his refuge, and with a last despairing cry ("Accursed Light, I feel thee now") he expires. A short choral passage, with harp accompaniment, brings this very dramatic and fanciful composition to a close:--
