warble
Sing with quavers
To warble is to sing with trills, quavers, or melodic variation—the way birds do naturally and humans do when showing off vocal agility.
A warble is such a song or the act of producing one: The canary warbled from its cage.
Separately, a warble is a hard swelling on an animal's back caused by a parasitic fly larva.
