Written in 1985, Marumba features a setting of one actual Puerto-Rican folk melody with several other newly created folktune-like melodies surrounding it. The work is light-hearted, but builds to a dramatic cadenza before returning to the carefree opening. Marumba was created with the Whitney-Alvarado Duo's love for flashy Carribean dance music in mind.
The Whitney-Alvarado Duo has performed Marumba throughout the Carribean. They also have performed the piece in several locations in the United States.
