Introduction to Tibetan Opera: Tibetan Opera is called "Ajilam" in Tibetan, which means "Fairy Sisters". It is said that it was first performed by seven sisters. Most of the repertoire is mythical stories from Buddhist scriptures, hence the name. Tibetan opera originated from Tibetan religious art in the 8th century. In the 17th century, it was separated from the religious rituals in monasteries and gradually formed a life-oriented performance that was mainly based on singing and combined with basic procedures such as singing, chanting, dancing, expression, speaking and skills. The singing tune of Tibetan opera is high-pitched and vigorous, and the music is basically determined by the person, and each line of singing is supported by a human voice. Tibetan opera was originally a square opera with only a drum and a cymbal for accompaniment and no other musical instruments.
