Bamboula is a quintessential example of Louis Moreau Gottschalk's synthesis of African-American Creole rhythms with European virtuoso piano traditions. It is distinguished by its driving, percussive intensity and complex cross-rhythms.
The primary challenge is the rhythmic vitality in the left hand against the rapid-fire ornamental figurations in the right.
