Laying out all musical instruments. What a great idea to not only get kids up and moving, but to learn colours as they go! I like this idea because it gives every child the chance to try each musical instrument.
Setar or Setouyeh is a three-cord instrument, which was converted into a four-cord instrument under the reign of the Qajars. It is, in general, an ancient and gnostic instrument usually played at the gathering of dervishes.
