Dilkash is the name of a mugham, one of the collections of melodic modes, each with its own emotional character, that are the basis of the classical Azeri repertory. Azeri classical music is a close relative of the Iranian classical dastgah repertory. Elshan Mansurov plays the kamanche in a deep, meditative style rare for Azeri music, which tends to be more extroverted. (During, Levin 2001)
