John Whelan, former WOMR radio host and author, teaches “The Art of the Duet,” a three-part Lifetime Learning course, from 1:30 to 3 p.m. on Thursdays from Oct. 10 through Oct. 24 at Snow Library. Accompanied by Peter Gaines on piano and Denise Page on vocals, Whelan will explore the aesthetic challenge of writing and arranging a proper duet and the art of the delivery. He’ll also use short films and video clips to illustrate.
