I am writing an article about an old traditional ceremony in Nimvar, one of the historic cities in Iran, which involves special music and a dance-like sport. This ceremony has been practiced for 2000 years to pray for rain. The main focus of this ceremony is a heroic sport played by farmers in Nimvar. However, I believe that the special music used in this ceremony is not merely a decorative element. Therefore, I am trying to find similarities between this music and the official elements of ritual music used in rain praying ceremonies. What do you think about the main characteristics of this type of music and dance throughout history? I would greatly appreciate it if you could share your experiences or recommend related sources. Sources about the Middle East, Mesopotamia, and ancient Iran would be most relevant to my work, but if you have any information about this type of music from around the world throughout history, please share it with me. Thank you.
