Beautiful. I love this Pas de Deux, and Simonov's choreography for this number is my favorite. Especially because he gave it to Nathanael (Franz) and Olimpia (Coppelia) instead of Clara (Swanilda)
At the very beginning of this exercept, there's the end of another number - is it the music before Clara exits the workshop, which I thought in 14:37-15:00 of Chemiakin's "fragments" video was a reprise of "Waltz of the Hours" (the moment it's implied Clara sees that Nathaniel has truly deserted her in favor of Olimpia and leaves out of heartbreak)?
Actually, scratch that - the instrumental at the beginning of this video was the last part of the "War and Discord" variation. Sorry for the confusion.
