The ritual performance takes place in the carnival period, and it consists of an animated and coloured nuptial train with a crescendo of sounds, cracks of whips, jingling harness bells, whirls of flowers and ribbons: its characters are armed with swords, others with whips, bells and high hats covered of flowers and dance around a married couple, while an odd red dressed personage (maybe the Devil himself) bounds and jokes among people.

Fusion between war and nuptial elements is typical of myths and ballads all throughout Europe, often mixed with a gay and festive spirit: they originate as real dramatizations of ancestral spring rites. Probably supernatural beings in the beginning, the actors of such pieces assumed then nature and appearance of real characters: the tyrant, the couple, the jester, the warriors and so on.

As a consequence it is not surprising to find out characters coming from different historical periods: La Lachera has been essentially folk feast from the very beginning and costumes were made up with available fabrics and cloths that villagers could collect each time.

That's why every stage of La Lachera's long lasting history left an enduring trace on its characters and choreography.

La Lachera traditionally develops around three dances: Lachera itself, Giga and Calisun. The first dance is incessantly danced during the nuptial train by the two Lachè, who trip elegantly along going forward and back reciprocally. Then both Lachè, the Bride and the Husband execute Giga followed by Calisun, when the Bride ritually chases twice each Lachè. Two other dances, "Curenta di Butej" and "Monferrina", were added only during the second half of last century and they are nowadays danced by country girls and muleteers, common figures in Rocca Grimalda's past.
