Giuseppe Verdi was always fascinated by the plays of Shakespeare; he wrote three operas based on them, and contemplated a fourth (based on King Lear) but was never able to find the proper libretto. Macbeth was the earliest of these Shakespeare adaptations, and a work which never quite satisfied the composer. The first version of the opera premiered in 1847 in Florence, but the version best known today is the revision the composer made for the 1865 Parisian revival. The changes include a new aria for Lady Macbeth in Act Two, the addition of a ballet scene for the witches, and the removal of Macbeth's death scene. In nearly every scene, there are at least some minor changes.
