John Field's Nocturne no. 4 in A Major provides the lyrical music for the beautiful pas de deux Comme on respire choreographed by Paris Opéra Ballet Master Eugene Polyakov for star dancers Charles Jude and Florence Clerc, who are seen in Roseman's sublime drawing presented at the top of the page and conserved in the Uffizi Gallery, in Florence. Polyakov, born in Moscow and trained at the Bolshoi Ballet School, became a respected teacher at the school and an esteemed choreographer in Russia and in the West. "Nureyev invited his compatriot to join him at the Paris Opéra as senior Ballet Master,'' recounts Roseman, who writes that Polyakov "upheld the perfectionism that Nureyev had instilled in the dancers of the Paris Opéra Ballet.''
