MONTRÉAL IN MOTION / SOUND

CORRESPONDANCE

An ambient soundscape shaped by Montréal transit activity.

Connecting to transit data…

LINE 1 — GREEN

1962 — 1978

The Green Line was one of Montréal’s two original Métro lines, opening in 1966 between Atwater and Frontenac. A decade later it pushed east to Honoré-Beaugrand for the Olympic era, then west to Angrignon in 1978, creating the cross-city route familiar today.

LINE 2 — ORANGE

1962 — 2007

The Orange Line opened with the original Métro in 1966, running from Henri-Bourassa to Bonaventure. Successive extensions from 1980 to 1986 carried it west to Côte-Vertu. In 2007, three new stations crossed the Rivière des Prairies into Laval.

LINE 4 — YELLOW

1963 — 1967

The Yellow Line was conceived to carry Montréal beneath the St. Lawrence to Île Sainte-Hélène and Longueuil. Completed in 1967 for Expo 67, its island station became one of the great gateways to the fair, handling 418,000 passengers in a single day.

LINE 5 — BLUE

1972 — 1988

Planned during the great expansion of the 1970s, the Blue Line finally entered service in 1986 between De Castelnau and Saint-Michel. New sections followed through 1988, completing the 12-station route between Snowdon and Saint-Michel.

STM BUS NETWORK

THE CITY ABOVE

Beyond the Métro, Montréal’s bus network carries the system into neighbourhoods across the island. At Métro stations, those surface routes converge with the underground network, creating thousands of daily correspondances between bus and rail.

Artist Statement

CORRESPONDANCE explores my developing relationship with Montréal through field recordings, transit, and sound. Built from recordings captured across the Métro and music composed around its iconic three-note chime, the piece transforms the movement of the city into a space for ambient listening. Brian Eno’s Music for Airports serves as a beacon for the work, exploring how transit hubs can become spaces for listening rather than simply passing through. Joshua Wolk’s trainjazz similarly inspired my use of transit data as a means of musical expression. Created as the Métro approaches its 60th anniversary, CORRESPONDANCE invites you to pause within the movement of Montréal.

How It Works

CORRESPONDANCE translates STM service activity into a continuously evolving soundscape. Each Métro line controls a musical layer derived from the system’s three-note chime, while bus activity shapes additional texture and field-recorded ambience. Live and scheduled transit data continuously reshape the mix, allowing Montréal’s transit network to influence how the composition unfolds. Change the day of the week and time to hear how the STM system’s activity changes throughout the week.
