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).

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.

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.

Joint application of the two techniques of “Lip” and “Nose” could be effectively applied for hearing and playing far-away intervals, by the Classical Guitar. Before this, a Classical Guitar player had to waive playing intervals not possible with the left hand, and had to replace or eliminate some notes, making it possible to play such intervals; specifically the capability of the left hand of the musician, was also a factor in such a selection.
