Siren Singing is a musical/voice-related magical ability that allows the user to put a person (usually a man) into an irresistible, hypnotic trance in which he will follow the mermaid around or obey the mermaid's whim and desires without question. Only natural mermaids have the power to sing like the legendary Sirens as Nixie stated that no human can sing better than a mermaid. However, the Full Moon can grant a human-turned-mermaid the voice of a Siren.

In this trance, the person does whatever they are told. In myths, sirens would sing their hypnotic tunes to attract and lure sailors to their deaths under the seas. The mermaids in the pod made the Enchantment Song strictly forbidden. However, Rita mentioned that sometimes when sailors or humans accidentally saw a mermaid, they need to be drowned and killed to preserve the secret, but since the Mako Pod forbid the Enchantment Song, they drown them by making a storm. In other mermaid pods however, it is unknown whether they allow the Enchantment Song to drown sailors.

In the Northern Pods, they have their own Enchantment Song. Their song can enchant mermaids from other pods, but not Northern mermaids, since they are immune as Mimmi reveals. In The Siren, Sirena watches a video of the Canadian Mermaid singing to a kayaker and becomes enchanted by the song. She becomes obsessed with David and follows him around. This song enchants a boy and makes him forget who he is, their lives, and invokes a desire to be with that mermaid.

The only way to reverse the Mako Pod Enchantment Song is to blow into a particular seashell. However, the Northern Pod's Enchantment Song's hold on a foreign mermaid can be broken if the Siren's voice is drowned out by the serenade of other mermaids and they sing the counter version of the Enchantment Song. When a mermaid used the Siren Song during the Full Moon effect, then the songs are reversed only when the full moon sets.

In Season 2 of Mako: Island of Secrets, whenever a mermaid sings a siren song, her voice has an echoed quality, like two voices speaking slightly out of sync. This may be an indication of magic being present in a mermaid's melody.
