Cooler heads may be prevailing at the Seattle Symphony, where news recently leaked out of an internal survey conducted by the musicians to express their dissatisfaction with the leadership of longtime music director Gerard Schwarz. The musicians now insist (contrary to some earlier reports) that the survey results were never intended to become public, and that they intend to settle their differences with the symphony’s board and management in-house. For his part, Schwarz is taking the high road, barely acknowledging the controversy and declaring that his relationship with the orchestra is “all about the music.”
