Drone (music)
Some Western Composers  liked to use a drone (especially one in fifths) to make it sound like bagpipes or other folk instruments.  Bach, François Couperin and other Baroque composers often called such pieces "Musette" (the French for "bagpipes").  Sometimes they did this in orchestral music: Haydn used a drone in the last part of his Symphony No. 104 to accompany a folk tune.
