When two LOUIS XIII cognac glasses touch to make a toast, they produce a G-sharp note—this inspired the creation of the ONE NOTE PRELUDE, a specially commissioned piece of music. The one-note symphony using only G-sharp was created by pianist Yaron Herman, exploring the idea of complexity within simplicity. Additionally, Ludovic du Plessis, LOUIS XIII Global Executive Director, also notes that the ONE NOTE PRELUDE "also expresses the complexity of one single note, as an echo to the tasting of one drop of LOUIS XIII Cognac, which lasts for up to one hour on the palate."
In the symphony, the sound of two glasses clinking together is created by a pair of robot arms. In April 2020, the robotic arms will be shown in LOUIS XIII Boutiques.
