Regional music festivals are organized to, firstly, introduce the music of different regions and, secondly, to support its performers. Regional music festivals are held in large cities for various reasons, including the availability of financial and executive facilities and the presence of an audience. However, the organization of these festivals has always been one of the challenging issues of ethnomusicology. The reason is that the presence of regional music performers in large cities places them in a context other than the context they would normally perform in their homes; consequently this change in situation leads to changes in the quality of their performance.

Carrying out the second phase of the project took more than 7 years engaging the new members of Reza Ziaei’s Workshop. In this phase, new researches were conducted from different aspects on the Qeychak and the modern versions of the instrument which were introduced previously by other instrument makers. The available versions of the instrument were studied in terms of their weak and strong technical features.

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.
