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.

Imagine that, in the course of historical research, we discover a musical piece whose compositional techniques (including form, melody, texture, and orchestration) resemble those of a second-rate 19th-century composition. But further investigation reveals that this work predates that period by 200 years. Can we still deem it insignificant? Certainly not. Here, the first major role of historical judgment becomes evident.

With this description, we have automatically included a criterion called “History”, Until we know the time of the creation of a work of art, we cannot judge whether it has been easy to create or not. Suppose that, in a historical study, we find a musical work that is similar in compositional techniques (including form, melody, context, and orchestration) to a minor work of the nineteenth century; however, our research proves that, this work dates back to 200 years prior to that date. Can we still consider this work insignificant? Definitely not! So this is where the first use of history-based judgment comes into play.

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 addition to the above-mentioned, polyphony can be also formed when a melody is performed by several singers in different ambiances or different sound registers according to their physiologic abilities.
