Weird name

In Tibetan Buddhism, a hungry ghost (or preta) is a being who is driven by an extreme need for emotional or physical fulfillment. In some traditions, hungry ghosts are thought to be the spirits of greedy people who have been reborn as beings who can never attain the fulfillment they so desperately seek. They are a metaphor for the impossibility of attaining illusory earthly desires.

A triad (chord) is a structural element of Western musical harmony.
