Art and craft
One element in this movie that has not received a lot of attention is the exploration of the difference between art and craft. And for those who know the movie you will be aware that by art I mean Camille and craft is Stéphane. And I use the words art and craft in their positive senses.
The movie explains that S. started out wanting to be a performer but did not like the sounds he made. C. knows when her violin is not sounding right, but it takes the equally unique craftsman to resolve the problem.
Camille is able to launch herself into space without regard for consequences. This is what gives her the 'tempérament' noted by Lachaume, which enables her to excel as a top performer. On the other hand Stephane is more solidly rooted, unable to convey to others his emotion which disqualifies him as a performer and artist. However his ability to remain grounded enables him to dispassionately, but caringly, help his friend end his life.
We tend to regard art as more admirable than craft, perhaps because it requires a rare personality. But clearly they are just different branches of the same extension of the human condition. Anyone else think the difference between art and craft is relevant here?
