Abstract
Faith music has existed with the emergence of belief since the archaic period and has been a tool in showing devotion to the sacred in almost all beliefs. Music is sometimes used individually, sometimes together with collective rituals, sometimes only with human voices, sometimes only with instruments and sometimes with musical accompaniment, in order to spread the belief, convey religious information and reinforce the teachings, purify, communicate with the spirits and present their devotion to them. In the study, the hymn "Ya Hannân Ya Mennan", which was performed in the tarawih prayers during Ramadan for centuries and constituted the ancient tradition of a city, was evaluated ethnomusicologically within the ethnology of faith music. The hymn "Ya Hannân", which is a type of Ramadan hymns, has settled in the memory of the people and created a culture as the public hymn used in mosque music during Ramadan in the city. It is so embedded in the cultural codes of the divine city that it is seen as a part of the tarawih prayer for some people, especially children, who have not left the province. When people who grew up with this culture go to the tarawih prayer outside of Sivas, they expect to listen to the hymn "Ya Hannân" in their sense of belonging when the hymns begin. It also concerns the discipline of sociology of religion because of the hymn that costs the whole city.
