Uthal is an opéra comique in one act by the French composer Étienne Méhul. The libretto, by Jacques-Benjamin-Maximilien Bins de Saint-Victor is based on the Ossian poems of James Macpherson. It was first performed at the Opéra-Comique, Paris on 17 May 1806. Méhul tried to give the work a dark, "Scottish" atmosphere by eliminating the violins from the orchestra and replacing them with violas.
Uthal has seized the lands of his father-in-law Larmor, who sends the bard Ullin to get help from Fingal, chief of Morven. Malvina, Uthal's wife and Larmor's daughter, is divided between love for her husband and her father and seeks in vain to delay the war. Uthal is beaten in battle and sentenced to banishment. When Malvina offers to follow him into exile, Uthal confesses that he has been wrong and he and Larmor are reconciled.
Uthal was part of the European vogue for the Ossianic poems of Macpherson. Another notable example from the time is the opera Ossian, ou Les bardes (1804) by Méhul's rival Jean-François Le Sueur. In fact, critics accused Méhul's librettist Saint-Victor of copying Les bardes, an allegation Saint-Victor rejected, claiming his work would have been ready in 1804 had it not been for a "host of obstacles".
Méhul's orchestration in Uthal is strikingly experimental. In his Treatise on Orchestration, Berlioz, an admirer of the composer, wrote, "Méhul was so struck by the kinship between the sound of violas and the dreamy character of Ossianic poetry that in his opera Uthal he used them constantly, even to the complete exclusion of the violins. The result, according to the critics of the day, was an intolerable monotony which ruined the opera's chances of success. This is what prompted Grétry to exclaim: 'I'd give a louis d'or for the sound of an E string!'" Part of this statement has been challenged. Edward Dent wrote, "It has been suggested that the opera would for this reason [i.e. the lack of violins] be unbearably tedious, but, as Sir Donald Tovey has pointed out, Uthal is in one act only and quite short, so that its peculiar colouring would hardly have time to become oppressive." In fact, contemporary critics praised Uthal, it was the public that was less enthusiastic and the opera was withdrawn after 15 performances.
