“IN BREVITATE MAGISTER EST” was written on the wee chamber organ onstage at Bourgie hall. This bad Latin is trying to say “there’s a teacher in brevity.” I don’t know if artistic director Isolde Lagacé was inspired by the device — one of a small collection of baroque instruments that I had no idea were tucked away in Bourgie — but the idea is well-reflected in a new series of 11 a.m. concerts,
the Baroque Matinées, which last about an hour and include commentary by Geneviève Soly.
