Both his parents were musicians, his father a horn player, his
      mother
      a singer; he learned the horn and singing and as a boy and sang in
      at least
      one opera in Bologna, where the family lived. He studied there and
      began
        his operatic career when, at 18, he wrote a one-act comedy for
        Venice.
      Further commissions followed, from Bologna, Ferrara, Venice again
      and Milan,
      where "La pietra del paragone" was a success at La Scala in 1812.
      This
      was one of seven operas written in 16 months, all but one of them
      comic.
      
       
      
      This level of activity continued in the ensuing years. His
      first
        operas to win international acclaim come from 1813,
        written for different Venetian theatres: the
        serious "Tancredi" and the farcically comic "L'italiana in
        Algeri",
        the one showing a fusion of lyrical expression and dramatic
        needs, with
        its crystalline melodies, arresting harmonic inflections and
        colourful
        orchestral writing, the other moving easily between the
        sentimental, the
        patriotic, the absurd and the sheer lunatic. Two operas
      for Milan
      were less successful. But in 1815 Rossini went to Naples as
      musical and
      artistic director of the Teatro San Carlo, which led to a
      concentration
      on serious opera. But he was allowed to compose for other
      theatres, and
      from this time date two of his supreme comedies, written for Rome,
      "Il
        barbiere di Siviglia" and "La Cenerentola". The former,
      with its
      elegant
        melodies, its exhilarating rhythms and its superb ensemble
        writing, has
        claims to be considered the greatest of all Italian comic operas,
      eternally fresh in its wit and its inventiveness. It dates from 1816;
      initially it was a failure, but it quickly became the most loved
      of his
      comic works, admired alike by Beethoven
        and Verdi. The next year saw
      "La Cenerentola",
      a charmingly sentimental tale in which the heroine moves from a
      touching
      folksy ditty as the scullery maid to brilliant coloratura apt to a
      royal
      maiden.
      
       
      
      Rossini's most important operas in the period that followed were
      for
      Naples. The third act of his "Otello"
        (1816),
      with its strong unitary structure, marks his maturity as a musical
      dramatist.
      The
        Neapolitan operas, even though much dependant on solo singing of
        a highly
        florid kind (to the extent that numbers could be, and have been,
        interchanged),
        show an enormous expansion of musical means, with more and
        longer ensembles
        and the chorus an active participant; the accompanied recitative
        is more
        dramatic and the orchestra is given greater prominence.
      Rossini
      also abandoned traditional overtures, probably in order to involve
      his
      audiences in the drama from the outset. In Naples the leading
      soprano was
      Isabella Colbran, mistress of the impresario, Barbaia. She
      transferred
      her allegiance to Rossini, who in 1822 married her; they were not
      long
      happy together.
    
Among the masterpieces from this period are "Maometto II" (1820) and, written for Venice at the end of his time in Naples, "Semiramide" (1823). Barbaia gave a Viennese season in 1822; Rossini and his wife returned to Bologna, then in 1823 left for London and Paris where he took on the directorship of the Théâtre-Italien, composing for that theatre and the Opéra. Some of his Paris works are adaptations ("Le siège de Corinthe" and "Moïse et Pharaon"); the opéra comique "Le Comte Ory" is part-new, "Guillaume Tell" wholly. This last, widely regarded as his "chef d'oeuvre", and very long, is a rich tapestry of his most inspired music, with elaborate orchestration, many ensembles, spectacular ballets and processions in the French tradition, opulent orchestral writing and showing a new harmonic boldness.
And then, silence. At 37, he retired from opera composition. He left Paris in 1837 to live in Italy, but suffered prolonged and painful illness there (mainly in Bologna, where he advised at the Liceo Musicale, and in Florence). Isabella died in 1845 and the next year he married Olympe Pélissier, with whom he had lived for 15 years and who tended him through his ill-health. He composed hardly at all during this period (the "Stabat mater" belongs to his Paris years); but he went back to Paris in 1855, and his health and humour returned, with his urge to compose, and he wrote a quantity of pieces for piano and voices, with wit and refinement that he called "Péchés de vieillesse" ('Sins of Old Age') including the graceful and economical "Petite messe solennelle" (1863). He died, universally honoured, in 1868.
