Stabat Mater is a work by Gioachino Rossini based on the traditional structure of the Stabat Mater for chorus and soloists. Initially he used his own librettos and compositions for a portion of the work and, eventually, the remainder by Giovanni Tadolini, who composed six additional movements. Rossini presented the completed work to Varela as his own. It was composed late in his career after retiring from the composition of opera. He began the work in 1831 but did not complete it until 1841.
In 1831 Rossini was traveling in Spain in the company of his friend the Spanish banker, Alexandre Aguado, owner of Château Margaux. In the course of the trip, Fernández Varela, a state councillor, commissioned a setting of the traditional liturgical text, the Stabat Mater. Rossini managed to complete part of the setting of the sequence in 1832, but ill-health made it impossible for him to complete the commission. Having written only half the score (nos. 1 and 5-9), he asked his friend Giovanni Tadolini to compose six additional movements. Rossini presented the completed work to Varela as his own. It was premiered on Holy Saturday of 1833 in the Chapel of San Felipe el Real in Madrid, but this version was never again performed.
When Varela died, his heirs sold the work for 2,000 francs to a Parisian music publisher, Antoine Aulagnier, who printed it. Rossini protested, claiming that he had reserved publication rights for himself, and disowned Aulagnier's version, since it included the music by Tadolini. Although surprised by this, Aulangier went ahead and arranged for a public performance at the Salle Herz on October 31, 1841, at which only the six pieces by Rossini were performed. In fact, Rossini had already sold the publication rights for 6,000 francs to another Paris publisher, Eugène Troupenas. Lawsuits ensued, and Troupenas emerged the victor. Rossini finished the work, replacing the music by Tadolini, before the end of 1841. The brothers Léon and Marie Escudier, who had purchased the performing rights of Rossini's final version of the score from Troupenas for 8,000 francs, sold them to the director of the Théâtre-Italien for 20,000 francs, who began making preparations for its first performance.
