Dee Moses, principal bass player of the Florida Orchestra, is the soloist this weekend in John Harbison's Concerto for Bass Viol and Orchestra. Moses is part of a group of 15 principal basses in orchestras across North America to perform the concerto, a process that began in 2006. The work was commissioned by the International Society of Bassists in memory of David Capoccioni, father of double bassist Hunter Capoccioni, and Michael Hammond, dean of the Shepherd School of Music at Rice University. It was funded by the Capoccioni family and participating orchestras.
Harbison, who composed The Great Gatsby for the Metropolitan Opera, chose the term "bass viol'' very deliberately. "The first movement,'' he wrote in a program note, "begins with an introduction which reminds the listener that the bass viol is the oldest instrument in the modern orchestra, grand survivor from the medieval viol family.''
The program includes Carmina Burana, with the Master Chorale of Tampa Bay and soloists. Christoph Campestrini conducts. Concerts are at 8 p.m. Friday at Morsani Hall of Tampa Bay Performing Arts Center, Tampa; 8 p.m. Saturday at Mahaffey Theater, St. Petersburg; and 7:30 p.m. Sunday at Ruth Eckerd Hall, Clearwater. $19-$54.
