Every now and then Berlioz let fly with his armoury of denigration and sarcasm, when he felt especially strongly that his subject had shown laziness, incompetence or poor taste.
This Jessonda belongs to the family of the Coras and Amazilys and the rest, who love a handsome stranger, almost always Spanish or Portuguese, whom a cruel priest wants to murder, and who, at the moment of climbing the stake or lowering themselves alive into the tomb, are rescued by their faithful lover. Jessonda has in addition a sister, whose charms have inspired a culpable passion in a young Brahmin; and he, moved by the prayers of the girl he loves, joins forces with the Portuguese and gives them the wherewithal to save Jessonda from the stake. Add some dancing girls who pretend to dance, some soldiers and priests who pretend to sing, and you’ll have a reasonably good idea of the interest and details of this drama, in which we find echoes of Fernand Cortez, Le Sacrifice interrompu, and Die Zauberflöte.
The score of Jessonda enjoys a certain reputation in Germany, but it's far from being Spohr's best work. On the whole, the Paris audience found it dull, lacking in character, short on excitement, contrast, and variety, short on ideas that are fresh, grandiose, or out of the ordinary, short on what ultimately gives life to music, especially to musical drama. The structure of scenes here often seems indecisive and truncated; we don't know when they start or when they stop; voices are frequently overpowered by the orchestra, and we especially find, to an irritating degree, the fault (with which Spohr has so often been taxed) of piling up disparate harmonies in the shortest space possible, in such a way as sometimes to place four or five different harmonies under a single note of the melody.
