The acoustic effect called "the Quetzal tail" comes from emitting an impulsive sound—short length but loud sound, an explosion, an applause or playing a percussion instrument—in front of the pyramid’s staircase. If we slap about 40 meters away on the perpendicular of the escalinata we hear a sharp sound, a strange squeak, a sound similar to the singing of the quetzal, the sacred bird of the Mayas. . . #Kukulkán #ChichenItzá Video Credit: @anilbrancaleoni | Jain 108 Academy
