Messa per Rossini

The Messa per Rossini is a Requiem Mass composed to commemorate the first anniversary of Gioachino Rossini's death. It was a collaboration among 13 Italian composers, initiated by Giuseppe Verdi. The composition was intended to be performed on 13 November 1869 in the Basilica of San Petronio, Bologna, where Rossini grew up and spent a large part of his life.

Verdi had proposed this collaboration in a letter from 17 November 1868, four days after Rossini's death, to his publisher at Casa Ricordi, Tito Ricordi (1811–1888), stating that after the performance, the manuscripts should be sealed in the archives of the Liceo musicale Rossini.

The city council of Bologna and the Accademia Filarmonica of Bologna received this idea favourably and a committee of three members (Lauro Rossi, Alberto Mazzucato, Stefano Ronchetti-Monteviti) of the Milan Conservatory was established in Milan with Giulio Ricordi as secretary. The committee chose the composers and assigned their tasks; Angelo Mariani agreed to conduct.

Mariani was also involved in Rossini commemorations in Pesaro, Rossini's birthplace, which were planned for August 1869. Despite Mariani's pleading invitation to Verdi on 19 August 1869, Verdi replied on the same day indignantly that he would not attend. In a letter from 24 August, Mariani expressed his distress at that response. Meanwhile, the committee had asked the impresario of the Teatro Comunale di Bologna, Luigi Scalaberni (1823–1876), to lend the performers, orchestra and chorus for the performance in Bologna on 13 November. Scalaberni refused on 6 October for commercial reasons because the performance of the mass would impede the success of his opera season. The municipal authorities then suggested to defer the commemorations until December, after the opera season. Verdi objected to such a delay and also to a suggestion by the committee to relocate the performance to Milan. In a letter from 27 October 1869 to Ricordi, Verdi rails against delay or relocation, and not only blames Mariani for the situation, but remarks: "Who would be the conductor at Milan? It cannot and must not be Mariani." The performance of the composition, which was finished by the summer of 1869, was then cancelled. The manuscript subsequently fell into oblivion.
