When Mark Johnston sits in his chair on a Saturday morning at the Ottawa Music Academy, it seems to swallow him up — even though it’s a kid-sized chair.
On this particular Saturday, his string ensemble is preparing for Discover the Arts, a free open house being held at the National Arts Centre from 10 a.m. to 5 p.m. on April 5. The Ottawa Music Academy is one of the hosts, along with the Ottawa School of Speech and Drama, the Ottawa School of Dance and the Ottawa School of Art.
