South Western Amazonian indigenous people often use song to “cure” people. Healing, however, depends on perspective: as healing is often achieved by overthrowing an assumed original causer of the illness, one’s benefit may result in another’s disaster. Being able to sing powerful healing songs implies that the reverse process is known too. An experienced healer with whom I worked even called the hallucinogen ayawaska “janson rao”, the “liar remedy”: a cure that can show you what you want to see, or what you are afraid of, something completely drawn by the hair, with perhaps an ounce of truth. The one-year learning that traditional medicos have to endure helps make sure they will make a difference. The Western Amazon singers, both healers and witches, are thus masters of seduction and deception. Even if their songs may seem soft and pleasant to the ear, they can also induce manipulations, deception, or even, in unfortunate cases, witchcraft and severe ill attacks.
