Fifteen years ago, the Canadian artist Elma Johnston McKay began to craft a set of keys in her native New Brunswick, Canada. Inspired by paintings and stories, religious and secular, she recognized that inspiration only sends the artist, the writer, the composer in search of a key. That it is the art of interpretation that unlocks understanding, that transforms the single into the universal, the season of despair into the season of hope. Changing Keys weaves a musical program, interacting with McKayʼs Keys, of Beethoven, Schumann, Harbison, Cage and Gershwin, and with readings of texts (selected by writer Jonathan Levi) ranging from the parables of Kafka to the diaries of Casanova to the dinner-table anecdotes of Isaiah Berlin. Music, words, and imagery combine to reflect on the ancient symbolism of keys as agents of transition.
