Rossini's contract required him to provide five new works for the Opéra over 10 years. After the première of Tell he was already considering some opera subjects, including Goethe's Faust, but the only significant works he completed before abandoning Paris in 1836 were the Stabat Mater, written for a private commission in 1831 (later completed and published in 1841), and the collection of salon vocal music Soirées musicales published in 1835. Living in Bologna, he occupied himself teaching singing at the Liceo Musicale, and also created a pasticcio of Tell, Rodolfo di Sterlinga, for the benefit of the singer , for which Giuseppe Verdi provided some new arias. Continuing demand in Paris resulted in the production of a "new" French version of Otello in 1844 (with which Rossini was not involved) and a "new" opera Robert Bruce for which Rossini cooperated with Louis Niedermeyer and others to recast music for La donna del lago and others of his works which were little-known in Paris to fit a new libretto. The success of both of these was qualified, to say the least.
