Tan Dun's creations can be unabashedly populist, radically experimental, or?most frequently?both. While his work does not neatly fit within previously-existing categories?perhaps the closest fit is opera in the broadest cultural context, Tan has created several new artistic formats, which?like opera?encompass sound, sight, narrative, and ritual. In addition to his contributions to the repertoire of opera and motion pictures scores, Tan?s new formats include: orchestral theatre, which re-contextualizes the orchestra and the concert-going experience; organic music, which explores new realms of sound through primal elements such as water, paper, and stone; and multimedia extravaganzas, which incorporate a variety of cutting-edge technologies.
