Giovanni Tadolini (18 October 1789 – 29 November 1872) was an Italian composer, conductor and singing instructor, who enjoyed a career that alternated between Bologna and Paris. Tadolini is probably best known for completing six sections of Rossini's 1833 version of the Stabat mater after the latter fell sick. However, he also composed eight operas as well as sinfonias, sonatas, chamber music, and numerous pieces of religious music and art songs.
