Characteristics of Vocal pieces of Music in the Yazdian Lamentation poetry for Ashura

The Ashura event influenced the composition of some of the melodies and types of music. In this article, the beauty of Yazd's lamentation, vocal music of Ashura poems, and their effects on the musical system are the subject of study.
