Tar is one of the most important classical Persian musical instruments. The exact place of origin of the tar cannot be confirmed. However Tar was invented in the territories of, or influenced by, the Persian Empire: Persia (Iran), Afghanistan, parts of the former Soviet republics, such as Armenia, Georgia, Azerbaijan. The word Tar itself means "string" in Persian.

The Tar appeared in its present form in the middle of the eighteenth century. It is a long-necked instrument and its body is a double-bowl shape carved from mulberry wood, with a thin membrane of stretched lamb-skin covering the top. The long fingerboards has twenty-six to twenty-eight adjustable gut frets , and there are three double courses of strings and is played with a small brass plectrum.
