Dear choral friends –
It is with the utmost sadness that the Elmer Iseler Singers acknowledge the passing of our dear friend and colleague, composer/pianist Ruth Watson Henderson. Ruth was a brilliant pianist, equally at home playing a piano concerto with orchestra as she was working with choirs, unfailingly kind and always generous in sharing her great talent. Ruth Watson Henderson has a long history working with the Elmer Iseler Singers and their predecessor, the Festival Singers of Canada, working closely for many years alongside Dr. Elmer Iseler as collaborative pianist to Canada’s first professional choir. She often credited Elmer Iseler for inspiring her to write for choirs as she listened to him rehearsing great choral works and discovering the colours she was able to create with the choir. It was the Festival Singers, and Elmer who inspired Ruth to write one of Canada’s greatest choral works, her Missa Brevis, a challenging work that revealed Ruth’s unique compositional voice to the world for the first time.
Her many works for choir and for organ following that compositional debut attest to her musical and creational genius. She was truly ‘one of a kind’, an exceptional and humble human being with extraordinary gifts, a true musical giant. The Elmer Iseler Singers have been honoured to be a part of commissioning, premiering, performing and recording Ruth’s music throughout many decades, experiences that have left us and our audiences enriched.
We will all miss her greatly, but her music will ring on through choirs across the country in joyous rhythmic musical lines, her unique voice an inspiration for the generations to come.
The Elmer Iseler Singers, Artistic Director Lydia Adams, General Manager Jessie Iseler and the EIS Board of Directors, James T. Chestnutt, Chair, send our deepest condolences to Ruth’s family and to her many, many friends throughout this country and beyond. In Ruth’s passing, we have lost a legend. May she rest in peace.
