That the film version of J. K. Rowling's wildly popular Harry Potter and the Sorcerer's Stone succeeds in re-creating the novel's magical atmosphere owes much to this richly imaginative symphonic score by John Williams. Of course, as the composer behind enchanting movie soundtracks from E.T. to A.I., Williams is no stranger to musical fantasy and wonder. He's the natural choice to provide the backdrop for young Harry's adventures at the Hogwarts School of Witchcraft and Wizardry. The music sets a fairy-tale tone from the outset, featuring a solo on the music-box chimes of the celeste, a distinctive sound that recurs throughout the score. But this opening tune isn't just fairy dust -- it also contains a hint of mystery, an omen of the wizardly potential Harry has yet to realize, and the dangers he will encounter as he does so. Williams's orchestration shows great variety, from the festive brass fanfares that herald Harry's arrival at Hogwarts to the swirling strings, harps, and wordless choruses that conjure up the supernatural world. Delightful episodes such as the frantic "Quidditch Match" allow free rein to the composer's creativity, while the ominous "Face of Voldemort" shows his ability to build a dramatic climax. By turns whimsical, otherworldly, nostalgic, and majestic, Williams provides the perfect musical backdrop, not only for the blockbuster film but also for rereading Rowling's irresistible novels.
