There aren’t many jobs for people who play viola, let alone top viola jobs.  The Twin Cities is rare for having two professional orchestras with viola sections. That’s what makes it possible for Maiya Papach and Rebecca Albers to chase their music dreams and create a life together in Minnesota.  Maiya Papach is principal violist of The Saint Paul Chamber Orchestra.  Rebecca Albers is the principal violist of the Minnesota Orchestra.   Coming up at 9 a.m. on Tuesday, MPR News host Angela Davis talks with the latest couple in her Power Pairs series about how to gracefully play a supporting role in music and in marriage.
