Music,
by the hour.

Dario writes music guidelines for boutiques, hotels and restaurants: their brand guidelines, for sound. Then, at every moment, the music follows them and adapts to the time, the light, the weather and the energy of the room.

A curator chooses what plays, the way a tailor cuts a suit: by hand, for one place alone. A player chooses when, depending on what is happening in the room.

A curator,
a player,
a place.

01

The music guidelines

Everything in the place was chosen: the light, the materials, the scent. Rarely the music. So a curator comes and spends time there, among the people who walk through it. From that visit come the place’s music guidelines, written for it alone: what its brand guidelines are to the eye, they are to the ear.

02

The choice

The curator leaves, the choosing goes on. Before every track, the player reads the moment (the light, the people, the weather, what has just played) and weighs the whole selection against it. Here, a real decision: 439 candidates, nine criteria each, nearly 4,000 scores for a single track. It invents nothing.

03

The chord

The music stops being laid over the place: it belongs to it, like its light and its materials. Everyone who walks in feels the difference.

One room, one day.

Its light, its people, its weather, and the music that answers them, track after track.

Without Dario

A playlist that could be playing anywhere: the same at eleven in the morning as at midnight.

 

With Dario

The music follows the light, the people, the weather and the energy of the room, moment by moment.

 

The Maestro

The heart of Dario. It sits by the sound system already in place, and it is connected to our technology, which listens to every track in the selection the way a music supervisor would: its energy second by second, its structure, its harmony, its rhythm, its timbre. Before each track, it weighs the whole selection against the moment, and chooses.
