"Ænema" is a song by rock band Tool, released as the third single from their second album Ænima. Adam Jones made a video for the song using stop-motion animation that appears on Salival. The song reached number twenty-five on the U.S. Mainstream Rock Tracks chart in August 1997.The song makes extensive use of hemiola, a musical technique in which the emphasis in a triple meter is changed to give the illusion that both a duple and a triple meter occur in the song.
