The Opening Musical Piece
Tchaikovsky - Violin Concerto In D Op. 35 - 3 Finale Allegro Vivacissimo (9:38)
– Lucifer's introduction
(first 30 sec)

This music piece found its inspiration in the composer's effort to recover from depression.
In 1877, Tchaikovsky undertook a very brief but disastrous marriage that resulted in his emotional collapse and attempted suicide. Fleeing from Moscow he found refuge in work and wrote this famous Violin Concerto.
In the film , Lucifer claims he was the one responsible for Tchaikovsky's failed marriage.
