How Open Amphitheater Acoustics Gave Birth to Theatrical Art Thus, the old street rituals honoring the God of Dionysus evolved staged performances, following written plays, that are considered as the foundations of dramatic theatrical repertory and are performed worldwide even today. In these open amphitheatric spaces, the acoustics were so appropriate that the performers-actors and the singing chorus could be seen and heard clearly in the most distant audience positions.
This is the age that saw the evolution of organized cities, the birth of democracy, the flourishing of philosophy, mathematics, and geometry. During the following centuries, after this early period, such public spaces progressively evolved into the properly-designed open amphitheatric form that appeared after the 6 th century BC.
