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. 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.
