La tua cantante

"They have a name for someone who smells the way Bella does to me. They call her my 'singer'— because her blood sings for me."

- Edward Cullen

La tua cantante is the Italian expression for a human whose blood particularly appeals to a certain vampire in an extreme sense. In English, it means "your singer", but is usually shortened to "singer" whenever someone in the series refers to her/him. The smell of each human is different, and certain humans can smell more appetizing than is usual to vampires. The more appealing any human's scent and taste is to a vampire, the more difficult it will be for that vampire to leave the human alive.

Infrequently, a specific human will smell nearly irresistible to a specific vampire. "Singers" are individual phenomena; a person whose blood sings for one vampire will not have the same effect on all vampires. While there are some humans whose scents are more appealing to vampires in general, that appeal does not reach the level of a singer.

Singers are considered by most vampires to be a great find, the drinking of whose blood is an experience to be savored.

Bella was Edward's singer prior to her becoming a vampire and Emmett once had two. Alice was James' singer before she was turned into a vampire. When Alice was turned, James was furious that he never had a chance to taste her blood. The blood of singers is described by Edward as being said vampire's "own personal brand of heroin". No one else is mentioned as being or having a singer. Aro was the first to refer to the term, and it was the first time any of the Cullens, besides Edward, had heard the term.
