Musette

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