The conductor in a samba band is often referred to as the "carnavalesco" or "maestro." The carnavalesco is responsible for overseeing the overall artistic direction and performance of the band, especially during Carnival parades. They play a crucial role in arranging music, choreography, and the thematic elements of the performance.
A material through which an electric current flows easily is called an electrical conductor. Many metals, especially silver and copper, are excellent electrical conductors.
