To honor their 25th year, San Francisco Area's Bay Bells has commissioned this handbell setting of Pablo Beltran Ruiz's well-known mambo tune, "Sway" ("Quien Sera"). The distinctive marimba sound is heard in the malleted bass bells while the trebles carry the infectious tune. The added percussion parts really give it that Latin flavor and offer opportunities for improvisation if desired. The tempo can be altered to give the piece an upbeat groove or slowed down for a more languid version. Percussion part: Conga, Guiro and Cowbell.
