The Setar (Persian: سهتار, from seh, meaning "three" and tār, meaning "string") is an Iranian musical instrument. It is a member of the lute family, which is played with the index finger of the right hand. Two and a half centuries ago, the fourth string was added to the setar which most of the time has the same tone as the bass string. It has 25–28 moveable frets which are usually made of animal intestines. They were made of silk in the past. The setar covers more than two and a half scales.

It originated in Persia before the spread of Islam, and has a close look and root to the Tanboor. But in the last centuries, the setar has changed more closely to the Taar, both in the tuning and playing style.
The satar (Uyghur: سه تار ; Chinese: 萨塔尔) is an important instrument in 12 muqam. It is a bowed lute with 13 strings, one raised bowing string and 12 sympathetic strings, tuned to the mode of the muqam or piece being played.
