Jesper Kyd composed the main theme commonly known as “Ezio's Family” for Assassin's Creed II.
The piece appears on the game's soundtrack and became one of the most recognizable musical themes associated with the Assassin's Creed series. Kyd's score combines orchestral writing with choral and electronic elements, matching the game's blend of historical drama and modern science fiction.
“Ezio's Family” is especially associated with Ezio Auditore, but the melody was reused and rearranged in later Assassin's Creed games. Its recurring appearances helped turn it into a musical signature for the wider franchise rather than only one character.
Jesper Kyd also composed the soundtrack for the original Assassin's Creed and later returned for Assassin's Creed: Brotherhood. Lorne Balfe, Sarah Schachner, and other composers contributed to scores for different entries, which is why soundtrack credits should be matched to the specific game.
