Finding a way to harmonize the Iranian music has been the subject of controversy among Iranian musicians for a long time. Some believe in the creation of harmonies for Iranian music based on a method which is similar to the tierce harmony; while others have either selected or invented some other methods. There are also some musicians who do not basically agree with the harmonization of the Iranian music.

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.

B. applying force: the force needed for putting finger on finger board is applied through finger tips and using the rest of hand set especially wrist is not allowed. To practice this, it is possible to hold violin without the bow and throw the fingers on the finger board from 1-2cm distance; apply force only through finger tips.

Mohsen Renani in the preface of his book entitled “The Political Economy of nuclear conflict; an introduction to traversing the civilizations” writes:

While the name “Persia” (Western historical name of Iran) has attracted tens of thousands of people from around the world to London’s British Museum to visit ancient Persian artifacts, the Nuremberg-based music company, Colosseum, invites Europeans to listen to eight masterpieces of Persian symphonic music.

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.

Daf is one of the percussion instruments associated with the Kurdistan region of Iran, which has a special place in Iranian music. In the past, animal skin was used for the drum head, but now most of the tambourines in the market are made with artificial skin, which are designed with various decorations.

In 1990  an Austria-based Persian musician Khosro Soltani, in cooperation with Hossein Alizadeh, put out an album entitled, Ancient Call A New (Nobang-e Kohan). After many years, a few ancient Persian instruments such as Sorna, Karna, Naghareh,etc. have been used, instruments which have been left out of the circle of Persian classical musical instruments for centuries.

ehrouz Mohammadi, “Daf and its feasts in Ghaderieh’s Tekyeh” mentions that the outer thickness of arch where studs are located, [is] between one to one and a half centimeters (Mohammadi, 2001: 12). The thickness of arch should be gradually reduced from the installation place of rings to skin (Avazeh of Daf) to create a high volume, clear sound from Daf; also, the connection of arch to skin should not be less than one millimeter, because in this case the skin will be torn due to the sharpness of the wood (Mogharab Samadi, 2009: 79-78). The thickness of wood on the skin side is about two to three millimeters (Tohidi, 2002: 79).

In this project, my specialized responsibility  was the basic drawings of the desired instrument with the help of engineering and mechanical software.  I have also the carried out phases related to engineering designs, related variables, and volume and weight calculations under Mr. Ziaei’s direct supervision from the very beginning. Regarding the challenges of this work, suffice it to say that the set of designs for the instrument lasted more than 9 months in the final stage of the project only.
