It's cheering to find how excited Berlioz is to be able, for once, to offer almost unstinted praise to a singer, in this case Delphine Ugalde.
It's rather a good idea to set the opera in the capital of French Africa. From this bizarre mixture of manners and costumes emerge comical contrasts and situations likely to lend unexpectedness and variety to the musical style. But these contrasts, piquant though they may be, cannot exempt the librettist from attaching an interesting plot to them and inventing a theme that is piquant and original. Unfortunately, it seems as though he said to himself: ‘Here's a frame, the composer will add the picture’. So, here's this frame in two acts, a gilt frame, decorated with pearls, muslin, lovely Arab heads, and French moustaches, not to mention the heads of Negros, a eunuch, and a muezzin.
I’m afraid I may commit more than one mistake in this analysis. Despite all my concentration, I took a long time to understand what was happening; words reached me only indistinctly or didn't reach me at all. The dialogue, written in verse, unlike the general usage of the Opéra-Comique, added to my puzzlement.
Clearly, in its physiognomy and comic nature, the opera is close to two works that have brought popularity to M. Grisar: L’Eau merveilleuse and Gilles le ravisseur, not forgetting Le Tableau parlant which Grétry was not alone in painting, and whose libretto did not merely make a frame. Here's what I thought was the plot of Le Caïd:
The curtain goes up, it's a square in Algiers, it's still dark with no sun in the sky. A small troupe of Arabs, marching in step, utters this familiar cry: ‘Be quiet! Let's hide! No movement! Let's be silent!’ (in verse, naturally). We gather that they’re stalking somebody and that they don't want to be spotted.
