Members of the St. Louis Symphony often build close connections with members of the St. Louis Symphony Youth Orchestra. Many of the musicians of the grownup orchestra teach YO musicians privately. And as part of the YO’s Beyond Rehearsal program, STL Symphony musicians come to Powell on Saturday afternoons to coach the YO in sectionals a number of times each year. YO auditions for the 16/17 season are coming to a close, and it is these kinds of learning experiences that make student musicians work so hard to get into the program. Video intern Nicola Muscroft spent some time with mentors and mentees and caught their interactions and their enthusiasms last spring.
