I'm quite certain that the music is entirely digitally synthesized...no real bowhair on tensioned strings with a human arm and fingers engaged in tone and pitch production was used. The music is basically a (bombastic) derivation of Bach's Prelude II in c minor from Book I of the Well-Tempered Clavier. I strongly prefer the original.
Not violins, plural, either - the young lady holds a viola.
Lovely photography and editing.
