Mohsen Namjoo - Persian Musician - Democracy Award Ceremony in Washington, DC on June 10, 2010. The award was given to the Iranian people, for their Green Movement, by the National Endowment For Democracy. The instrument being played is a Setar (pronounced seh-tar), and has 3 strings. The "Seh" is Persian for "three", and "tar" means "string".
I believe the setar was originally a 3-string instrument (that is how it translates directly) but a fourth string was added a couple hundred years ago and is now the standard.
