Or more?” writes Howard Reich in Wednesday’s (5/13) Chicago Tribune. “What hap-pens to the musicians’ sonic brilliance …their unanimity of thought and phrase and tone? … The Chicago Symphony Orchestra musicians, like their counterparts … around the world, ponder these questions.… CSO music director Riccardo Muti [says] a long quarantine … ‘will affect not the quality of the orchestra but the morale of the musicians.’ … CSO principal percussion Cynthia Yeh says, ‘What has been shocking to me is how hard it is to play even a duo when you’re not in the same room.’ … The musicians’ isolation reflects everyone else’s.… ‘I am playing alone every day at home, practicing with my mute,’ so as not to disturb neighbors,’ says principal trumpet Esteban Batallan….
