They’ve become a true Montreal icon. Just as we eagerly await the return of hot summer days, 21 Balançoires/21 Swings trigger our thirst for spring and the chance to be part of the installation’s beautiful music.

It’s more than just a playground toy and more than a musical instrument: this collaborative work has become, since its first presentation in 2011, nothing less than a catalyst for change in the Quartier des Spectacles.

Here are seven little-known facts about the musical installation 21 Balançoires/21 Swings returning for the ninth straight year until May 28.

1. One is fun, but 21 is even better!

Each swing produces sounds on its own, but the work is designed to encourage people to collaborate. As people focus on coordinating their motions and listening to the music, the soundtrack grows more interesting and complex. “The idea of collaboration set the tone for the piece, and for the research we’ve done since the first presentation,” explains Mouna Andraos, co-creator, with Melissa Mongiat, of 21 Balançoires/21 Swings.

2. Swinging like the animals we are

To optimize the collaborative experience, the Daily tous les jours team worked with Luc-Alain Giraldeau, a university professor who’s an expert in behaviour – animal behaviour. After all, people are animals too!

3. A complete symphony

The swings reproduce the sounds of four instruments: piano, guitar, vibraphone and harp. Each one corresponds to a swing of a different colour, while the height reached by the user determines the note played.

4. Bringing people together

The 21 Balançoires/21 Swings break down barriers. The installation helps people meet and collaborate. Thanks to the Knight Foundation grant, Daily tous les jours studied the social and economic impact of the installation in 2017. “21 Balançoires/21 Swings represent the future of our cities,” Mouna Andraos argues. “The installation shows how we can live together, reclaim public space and create gathering places.”

5. Lots of swinging!

Every day, each swing moves some 8,500 times. Imagine how many people have played with 21 Balançoires/21 Swings since its unveiling nine springs ago!

6. Unexpected success

First presented in 2011, 21 Balançoires/21 Swings were intended to be a temporary piece. But in light of its incredible success, the installation has become a tradition and returns every spring. “At first, it was going to be five weeks and done,” says Mouna Andraos. “We never thought the installation would still be presented in 2019, and we’re very proud that it is!”

7. For ages 5 to 105

The 21 Balançoires/21 Swings are far from being just for kids. They’re actually for the child we all have within us. Each spring, the colourful seats hold a succession of blond, brown, grey, dyed and bald heads. Memories and nostalgia for childhood swings attract people of all ages to the installation.
