Harmonies or melodies which are made up of the pitch set of a major or minor scale are called drones.
What are drones?
- A drone, French bourdon, is a prolonged tone in music that provides a sonorous foundation for a melody or melodies that sound at a higher pitch level.
- Drones are harmonies or melodies composed of the pitch set of a major or minor scale.
- A drone is a harmonic or monophonic effect or accompaniment in music in which a note or chord is constantly sounded for most or all of a composition.
- Drones can be loud because their propellers move quickly through the air and quickly displace significant amounts of air.
- As the propeller spins, this causes pressure spikes, resulting in a characteristic buzzing noise.
- The quick action of the propeller blades, as well as the exertion of electrical motors, generate a lot of noise.
Therefore, harmonies or melodies which are made up of the pitch set of a major or minor scale are called drones.
