Symon Henry’s artistic practice is based on the interaction between three major axes in his creations, namely concert music, visual arts and poetry. This transdisciplinary approach is particularly reflected in his graphic scores — instrumental or performative — which have been interpreted in North America, Europe and Asia by ensembles and soloists such as HSO-Stuttgart Symphony Orchestra, SurPlus Ensemble, Nouvel ensemble moderne, Joseph Petric and Kasia Kadlubowska. His first collection of poetry, son corps parlait pour ne pas mourir, as well as his first art book of graphic scores, voir dans le vent qui hurle les étoiles rire, et rire, were published in 2016 at Éditions de la Tournure. His visual art work has been exhibited at Gham & Dafe, Livart, Maison de la culture du Plateau-Mont-Royal, Chapelle historique du Bon-Pasteur, and at the Palazzo Ducale di Lucca.
His work voir dans le vent qui hurle les étoiles rire, et rire, a 40-minutes piece co-composed with Yannick Plamondon for the Orchestre symphonique de Québec and marimbist Anne-Julie Caron, was performed in September 2016 to celebrate the inauguration of the new Lassonde pavilion of the Musée national des beaux-arts du Québec. Symon is Génération2016 laureate and has taken part in the Ensemble contemporain de Montréal Canadian tour.
