Answer :
Drone is a sustained tone.
A minimalist style that emphasizes the use of prolonged sounds, notes, or tone clusters known as drones is called drone music, drone-based music, or just drone. Long audio programs with just very small harmonic fluctuations throughout each piece are often its defining characteristics. One of its founders from the 1960s, La Monte Young, described it as "the sustained tone branch of minimalism" in 2000. Didgeridoo music in Australia, South Indian classical Carnatic music, Hindustani classical music, and bagpipe traditions, among others, are all examples of music that contains drones and is rhythmically still or very slow, often known as "drone music" (both of which are accompanied almost invariably by the Tanpura, a plucked, four-string instrument which is only capable of playing a drone)
