In the history of Iranian art and literature, the term Ghazal was not only used to introduce a poetic form. This word has another specialized meaning. The other meaning is a musical term and it is related to combination of poetry and music. In ancient Iranian music, this term means a kind of ballad as a part of a larger genre called Nobat-e-Morattab (a musical suite) it seems that in Hafez's poetry, both meanings of this term are used in a self-aware and deliberate manner to suit the subject of the poem. The present study tries to use an inductive method by taking advantage of the literary industry to consider the analogies and the existing semantic clues, from a part to whole in three levels of intra-verse, inter-verse and finally inter-poetic, first to show the types of usages of these terms by Hafez and then in Comparison with its use by other poets to reach a more exact view about Hafez's relationship with Iranian music rather than previous studies. This research tries to uncover an aspect of Hafez's relationship with music with a scientific method and show how the relationship between Hafez and music can take on a specialized form. The present research will be able to cover the hypothesis of Hafez's familiarity with music in a scientific and reliable way.
