On our tenth anniversary, we're launching a composition competition to redesign this auditorium signal: a small but meaningful sonic ritual, transformed into a distinctive gesture of welcome and identity.

Among the many gestures that structure the experience of live performance, one often goes unnoticed: the short sound that invites audiences to take their seats. A purely technical cue – yet one that marks a subtle but crucial transition: from outside to inside, from noise to silence, from waiting to listening.

The challenge is to imagine a sound that is both functional and imaginative. A signal that cuts through the ambient noise of the foyer, yet without commanding or intruding. Something brief, clear, memorable—but never jarring. In a world saturated with alerts, ringtones, and digital notifications, this competition invites composers to imagine a different kind of signal—one that doesn’t instruct or interrupt but invites and prepares.

The winning proposal will be developed in close dialogue with the LAC team and jury, with the aim of becoming not just a signal, but a signature – a sound that quietly says: you’re here, and it’s about to begin.
