Determining the originality of the art objects are always a big task for evaluators. Those objects which have woods in their structures have the chance of using tree-rings pattern as a sign of originality. TAR is one of the most popular Iranian musical instruments which can be considered as one of the national musical instruments of Iran. The construction of today’s TARs started about the year 1890 in Isfahan. Some of the most famous producers of TARs were YAHYA, ABBAS and JAFAR. Due to the value of their products, a lot of collection owners claim that they have some of these famous TARs. Isfahan musical museum have two TARs which one of them is claimed to be made by ABBAS (TAR II) and another by JAFAR (TAR III). For investigating these claims, the mentioned TARs were compared chronologically with one original ABBAS sample (TAR I). For this purpose, a Canon EOS 6D camera, ImagJ software and TSAP-Win software has been used to take photo-graphs, analyze photos, measure the annual rings distances and cross date of the TAR’s woods. Results illus-trated that annual rings in all directions in TAR II and TAR III are compatible with the original sample (TAR I). It seems that used woods for producing all three TARs have similar chronological characters and it can be approved that production period of TARs and original region of their woods are almost the same in the middle of 20th century.
