“Music, chanting, and dancing are indispensable elements of the Phi Fa ritual. The khaen, a bamboo mouth organ, is the primary musical instrument of the ritual. It is creates a sacred atmosphere accompanying ritual prayers and devotions and encourages dancing around the sacrificial altar. The khaen is accompanied by the phing, a guitar-like stringed instrument, by a drum, and by ching, small bells, cymbals. The chanting is very similar to mor lam, the traditional music of Lao and northeast Thailand.

Phi Fa ritual participants dance around a decorated sacrificial altar. The dance lasts a full night and creates trance conditions for many of the participants. They believe Phi Fa will participate the ceremony and they expect healing and protection from unfavorable fortune.

The steps of the ritual are related to the songs chanted by the shaman and are always accompanied by the khaen. This is because the khaen is believed to be an important mean to communicate with the gods and the spirits. The steps of the ritual are as follows: inviting the gods or spirits, explaining the reason for the invitation, praying for assistance, praying for protection, consoling the patient, re-calling the spirit that has fled the patient, inviting Phi Fa to accept the offerings, Baasii ritual, fortune telling, and taking leave of Phi Fa.”
