Abstract: A mobile scenery arrangement is provided which is easy to assemble and dismantle, and which can easily be transported, stored and used with uniform curtains and a uniform set of back-drops for the same performance. The mobile scenery arrangement includes a tubular construction forming a substantially vertical left side and a substantially vertical right side, the left and right sides being joined to at least one upper front curtain rod and at least one upper rear back-drop rod via corner members. At least one of the ends of the front curtain rod and the rear back-drop rod is provided with a cord-tensioning device arranged to steplessly stretch a cord between the two ends of the rod. The cord is arranged to displaceably carry curtains or a back-drop.
