Traditional iranian dastgāh music, as fostered in the courts and the homes of the aristocracy, draws from many sources, including regional music styles, religious genres of melody and chant and popular songs that have been reworked by master musicians and their students. In different regional capitals, musicians acquired their repertoire from their master teacher through a process of listening and repetition and also drew from local sources of music, incorporating these into their own unique version of this repertoire of traditional melodies and melodic fragments.
