Céline Dion’s highly anticipated residency at the Plenitude Arena in Paris, which began on September 12, is entering its fifth concert. The event has drawn large crowds, but it has also sparked mixed reactions online. Some social media users have expressed disappointment, claiming that Dion’s voice has changed and that she may not be singing as she once did. Critics have suggested she may be out of tune or using playback, a technique where a pre-recorded vocal track is played during a live performance. Others have even advised her to retire, citing the high ticket prices and their perception of imperfections in her singing. Marlène Schaff, a singer, actress, and vocal coach, attended Dion’s first concert in Paris and has spoken out in defense of the Canadian icon. Schaff acknowledges that Dion’s voice is not the same as it was before, attributing the change to six years of suffering from stiff person syndrome, a rare neurological disorder that causes muscle stiffness and spasms. Schaff explains that the condition has affected Dion’s vocal apparatus, requiring her to adjust the pitch of some songs. "It's true. Her voice is not the same, and so what?" Schaff says, emphasizing that Dion’s strength lies in her resilience rather than the perfection of her voice. Schaff also addresses the claims of off-key notes, suggesting that such issues are common among artists, especially at the start of a performance. She attributes them to stage fright, the long break from performing, and the emotional intensity of Dion’s show. Schaff notes that Dion was visibly emotional during the concert, even crying at times, which she says is a sign of sincerity. She also questions whether the increasing use of auto-tune—a technology that corrects pitch in real-time—has raised audience expectations for perfection, making it harder for artists like Dion, who do not use such tools, to be judged fairly. Despite the criticism, many fans have traveled long distances to see Dion perform, drawn by her legendary status and the emotional impact of her music. Schaff highlights the overwhelming support Dion has received, noting the standing ovation she received after stating, "There is one thing I can tell you in three words: I'm fine." Schaff describes Dion as one of the strongest women she has seen on stage, emphasizing that her music brings comfort and light to those who need it. Dion herself has spoken about her journey with illness, saying, "I have learned to live with this fragility. Through constant companionship, I have tamed it and decided to make it the strength to live." Her return to the stage, despite the challenges, serves as a powerful reminder that nothing is impossible.
