As the Cincinnati Symphony prepares to announce its 2006-07 season, music director Paavo Järvi is turning up the heat on one of the orchestra’s most pressing issues – its concert hall. “With 3,516 seats, it’s the largest concert hall in the U.S., and despite having an audience any orchestra in the country would be proud to own (the CSO has more long-term subscribers than any U.S. orchestra), the cavernous hall swallows them up… There has been considerable speculation about ‘downsizing’ Music Hall, which was never intended as a concert hall in the first place, the CSO having left its home in Emery Theatre in 1936 to give Music Hall an anchor tenant.”
