Bergamask, bergomask, bergamesca,[1] or bergamasca (from the town of Bergamo in Northern Italy), is a dance and associated melody and chord progression.
It was considered a clumsy rustic dance copied from the natives of Bergamo, reputed, according to the Encyclopædia Britannica Eleventh Edition, to be very awkward in their manners.
'"Twentieth-century Italian composer Ottorino Respighi adapted the melody as the final movement of his Suite #2 of Ancient Airs and Dances.
The title of Claude Debussy's Suite bergamasque is a poetic reference and the piece is not related musically to the Bergamask described here.
The characteristic I-IV-V-I progression features in popular music of the late 20th century, for example the song "Twist and Shout."
