The Symphony controls everything . . . the Symphony IS everything. And when an angel or demon wants to bring the Symphony more in tune with his own desires or those of his Superior, he uses a Song. This book includes more than 300 new Songs - to create, to destroy, to change. Some are usable only by angels, some only by demons, and a few are even available to mere mortals.

Liber Canticorum also includes special rules for each Choir and Band, giving them advantages with certain Songs, and guidelines for discovering powerful lost Songs -- or creating new ones.
