Jesper Kyd composed the musical score for Assassin's Creed II, including its celebrated main theme.
Kyd's score combines orchestral writing, choral textures, electronic sounds, and period-inspired colors to support Ezio Auditore's story in Renaissance Italy. The track commonly called “Ezio's Family” became one of the most recognizable pieces associated with the Assassin's Creed series and was later reused or rearranged in subsequent entries.
The music was released alongside the game in 2009 and helped establish a sonic identity distinct from the first title's score. Kyd also composed music for the original Assassin's Creed and Assassin's Creed: Brotherhood.
Lorne Balfe scored Assassin's Creed Revelations, while Sarah Schachner contributed to later games including Origins and Valhalla. Austin Wintory is associated with other video-game scores, so these composers are plausible but incorrect alternatives.
