Surrounded by two groups of artists lending rhythm to the act with their voices and percussion work, three acrobats redefine teeterboard technique in an act where speed is rivalled only by complexity.

The first half of Corteo ends with a bang as the cast takes to both sides of the stage forming two opposing factions singing, chanting and clapping in time to the catchy melody. Drummer/percussionist Kit Chatham stands on the edge of the outer turntable and pounds out the pulsating rhythm that accompanies the Teeterboard (Korean Plank) act. The act is performed by two young men (alternating between Stéphane Beauregard, Jérémie Robert and Petar Stoyanov) who propel each other ever higher and perform increasingly daring flips before landing back on the plank. This act is simply astounding not only for the high skill level but also the inventive staging. The atmosphere is intense, like a street fight, and each of the two factions on stage chant and cheer their champion. The first act closes with the two combatants reconciling and the entire cast breaking out into a rendition of the catchy Teeterboard theme as the scrim curtain descends for intermission.
