Persian ritual music

Persian ritual music (sometimes called "Iranian Ritual Music") (Persian: موسیقی مذهبی ایران) is a type of Persian music which is used for religious ceremonies.
"Persian religious music" can be used for various religions which are practiced in Persia/Iran such as Islam and Zoroastrianism.
The ethnomusicologists such as Mohammad-Taghi Massoudieh did research about Persian ritual music. Massoudieh also published a book in Persian in this issue.
