It is clear that The Tempest depends for much of its success on a wide range of special effects such as sound, lighting, and fantastic visions of the natural and supernatural worlds. Ariel, the mystic spirit, and his cohorts provide some eerie and some wondrous musical sounds, painting pictures with their voices of settings the audience saw. For example, when luring the spellbound Ferdinand towards his future wife, Miranda, Ariel and his fellow sprites caress the shipwrecked prince with harmonious notes which captivate even the crowd.

Also, when Ariel is first presented to the audience, Prospero is displeased with the sprite and reminds him that he is simply a servant by binding him to the ground with an unnatural force described by sounds of steel beams meshing and a dull green
