One of the most important criteria for measuring the quality of a piece of classical music is number of times the piece has been performance by different ensembles and orchestras in different eras. This belief has become so pervasive in some societies, such as Iranian society, that it is considered the only criterion for measuring the quality of a piece of classical music.

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).

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.

Tajvidi thought of studying harmony and orchestration with Houshang Ostvar (who was eight years younger than him) at a time when he had gained a reputation among musicians. His humbleness, making him willing to kneel before the scholars at any age and position, became the key to his scientific success. After this period, Tajvidi made some of his works polyphonic, the most prominent of which is “Burn” set to a poem by Abdullah Ulfat. However, his ability to make his works polyphonic was not so great to make him self-sufficient; so he depended on musicians such as Farhad Fakhreddini, Fereydoun Naseri, Kambiz Roshanravan, Fereydoun Shahbazian and Morteza Hananeh for the arrangement of his compositions.
