Diapason translates to "tuning fork". It's a specific and somewhat rare word that immediately evokes a musical context, making it interesting for a song about music.
In the song, the tuning fork symbolizes harmony and agreement among the musicians. When Eléonore leaves, taking the diapason with her, it signifies the loss of their shared musical purpose and the eventual dispersal of the group. It's a poignant metaphor for how a small, essential item can hold a group together.
Picture three young friends crammed into a living-room full of sheet music and half-tuned instruments. Every Thursday they wrestle with the same tricky fugue, a piece so beautiful that when Eléonore begins the theme on piano the others stop playing just to listen. Between missed notes, broken strings, and neighbors knocking on the wall, they laugh, restart at “fa-mi, fa-mi-ré,” and break for afternoon snacks while cheerfully saluting their unseen mentor, Jean-Sébastien Bach.
Maxime Le Forestier turns this lighthearted rehearsal scene into a tender ode to friendship and nostalgia. When Eléonore eventually leaves with the tuning fork, the little trio drifts apart, yet the fugue itself lives on like a time capsule. Every time the singer hears those familiar harmonies, spring returns, memories bloom, and the magic of making music together feels as fresh as ever. The song reminds us that even imperfect performances can create perfect moments that last a lifetime.
