If someone peeked into the studios of McKnight Hall this week, one could have found Pat Wheelhouse encouraging a group of fifth-graders to play a D major scale on mountain dulcimers in front of them. On the other side of the building, 78-year-old Linda Hubert could be heard shouting over rows of autoharp-playing students who strummed up a dull roar. And if someone just happened to be walking by the School of Music campus, the syncopated ruckus of a jazz band was hard to miss.
