Sea Shanties, also known as Song Sheets, are musical collectibles in Assassin's Creed Black Flag Resynced that enable your Boarding Crew to perform different shanties while sailing your ship outside of combat. While these collectibles offer no intrinsic value beyond their musical performances, they serve to enhance the atmosphere during sea travel. A total of 45 Sea Shanties are available to collect throughout the Caribbean map.
To gather a Sea Shanty, players must navigate to its marked location. Upon arrival, the Song Sheet will appear to float across the skies, requiring the player to pursue it to its final destination before it is added to the player's collection. This chase mechanic is integral to acquiring each shanty.
Once collected, Sea Shanties can be enjoyed when the player's ship, the Jackdaw, is at sea and not engaged in combat. As more shanties are collected, the crew's repertoire expands, offering a greater variety of songs. Players can cycle through the available shanties by pressing right on the D-Pad. For those songs that are particularly favored, pressing down on the D-Pad will open a favorites menu, allowing for quick access to preferred shanties in the future. This feature is designed to boost crew morale between naval engagements.
