The piece takes as a model the form "Variation" from the musical tradition, but this time the theme is not musical but literary: 5 people discuss a strange event that happened “yesterday".
The work develops 21 variations on the theme and proposes a journey from a naturalistic treatment of the word towards an increasingly complex and musical organization. 

The play was premiered by the “Atelier de Théâtre Musical” of the Hochschule der Künste Bern (Switzerland) in 2014.
