Denise Duval revisitée ou La « Voix » retrouvée (1999)

Denise Duval, the great soprano, friend and muse of the composer Francis Poulenc, who in 1959 created the role of the woman whom her lover left by telephone in "La Voix humaine", who replayed the role a decade later in front of the cameras of the film-maker Dominique Delouche, accepted that the same Delouche filmed her giving a masterclass to Sophie Favier, a soprano of the rising generation, passionate about Poulenc's music.
