Tanboor it is the oldest string instrument in Iran. In 800 B.C a kind
of Barbat was used. In some books the invention of this instrument is a
scribed to Barbad. As it is told in some books, the reason to name this
instrument Barbat is that this name is the Arabic form of Barbad, but
in some other books it is told that Bat means chest, so the similarity
between the form of a Barbat and the chest of a drake is the other
reason for its name. After Islam’s attack to Iran this instrument was
taken to Arabia and after a while it came back to Iran with a bit
change in it. For Islamic culture penetrated in to Europe, this
instrument was used is some parts with different names , for example in
Italy it was called "Lotto", in France "Loth" in Portugal "Aland"
a and in Spain "Loud". This instrument was abolished in Safavidth
period by an unknown reason (maybe because of the religious
fanaticism), even till recent decades. This instrument was used again
by Master Mansour Nariman.
