No introduction is needed when talking about the position of the late Houshang Zarif (1938-2020) in the Iranian music. His character and personality are so well-known among musicians that his name per se is a symbol and role model for the Iranian youth. “Becoming Houshang Zarif” is the dream of many young people who enter the world of music in Iran and many of whom retire regretting the realisation of this dream.

In the world music culture, there are instruments which were traditionally associated with a certain gender. It remains disputable to what extent these gender-based perceptions have been logical and scientific. For example, as playing wind instruments need more breath strength and the public opinion believe that men have stronger breath compared to women, these instruments are predominantly a male domain. Harp is also considered a female instrument as the public opinion believe that women have finer fingers and can therefore better perform nuances and delicate techniques on the instrument.

With this description, we have automatically included a criterion called “History”, Until we know the time of the creation of a work of art, we cannot judge whether it has been easy to create or not. Suppose that, in a historical study, we find a musical work that is similar in compositional techniques (including form, melody, context, and orchestration) to a minor work of the nineteenth century; however, our research proves that, this work dates back to 200 years prior to that date. Can we still consider this work insignificant? Definitely not! So this is where the first use of history-based judgment comes into play.

In heterophonic variant, two performers perform a single melody simultaneously and change it. Performing and changing a single melody simultaneously by two performers leads to the coincidence of different voices.

Discussions and research have been conducted on the harmonization of “dastgah” and melodies in Iranian music, and several books have been published on this topic, including “Armenian Music of Iran” by Ali Naghi Vaziri, “Harmony of Iranian Music” by Farhad Fakhreddini, and “Harmony of Iranian Music” by Ali Ghamssari. A master’s thesis titled “Presenting a Solution for Harmonizing Based on the Structure of Tritone Intervals” was written by Atefeh EinAli in 2014. Additionally, the invention and use of “Even Harmony” by Morteza Hannaneh should be mentioned.

In addition to the above-mentioned, polyphony can be also formed when a melody is performed by several singers in different ambiances or different sound registers according to their physiologic abilities. An example of this has been performed in rituals of Khanqah of Ghaderi darawish of Mahabad[i].

In the tradition of classical music, it is generally tried to use the same technical terms related to music in all countries. Even in the cultures in which native terms exist to refer to musical terms, usually the better known universal terms are employed.

In response, it should be said that it is better for the national anthem of a country to use the musical material exclusive to that country; however, some problems might come up in doing so the most important of which include: lack of familiarity of other countries’ music performer with the concerned country’s specific music intervals and special musical technique; and secondly, the strangeness of that music to the foreign listener.
