Regarding the classification of a new instrument in an instrument family, one can point to a number of fundamental issues, one of the most obvious of which is the instrument’s visual features. If we look at how the new instrument has changed compared to its historical versions, the set of visual elements that link the instrument to the Qeychak family becomes apparent. But other characteristics such as the geometric dimensions of the instrument, characteristics of the instrument’s various parts and how they relate to each other, its systematic performance, its sound range (compared to modern versions), the material and color of the sound, the way it is played and the like, can be considered in order to classify the instrument in the Qeychak family.

The Structure of Kurdistan Daf (V)
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).

A combination of technique and musicality in the fingers of a pianist
In the world of classical music, the position of soloist has always been exceptional. Apart from the technical ability that many orchestral musicians also have, the soloist must also have a special power to be able to present a different and unique perspective of a piece. The soloist must maintain its special power of expression not only in solo roles but also when interacting with the orchestra.

Last Year under the Light of Music

Interview with the Makers of the New Qeychak (I)
On occasion of the 8th anniversary of launching HarmonyTalk Online Journal on 6 April 2012, Reza Ziaei, master luthier and researcher on classical music instruments (violin family), announced that the first phase of the project to improve Qeychak has borne fruit. The new instrument would feature a bowl of ribs and the material used for the surface would be wooden. 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.

The Structure of Kurdistan Daf (II)
With its simple physical structure and captivating sound, the Daf never belonged to a particular culture or location, and every nation had different usages for this instrument considering their dominant customs and traditions.

Negation of Changes in Iranian Music: Embracing Tradition
The perspective that denies any alteration or innovation beneath the realm of Iranian music, and more broadly, the performance and even the structure of Iranian music instruments, stems from the discourse of “tradition-oriented”* and the “return to self” movement in Iranian music. Given that some educators still adhere to this discourse and emphasize the necessity of preserving tradition, a perception is formed among art students that Iranian music, including Radif, lacks dynamism and is confined within a rigid framework.
