As a young man Hare performed as a concert violinist.[4]
Hare joined the music department at Mount Allison University in Sackville New Brunswick, and took over the direction of the Mount Allison College Symphony Orchestra in 1945.[2] In 1949 he founded the Calgary Symphony Orchestra, composed largely of musicians from the Mount Allison music program.[5] The Symphony played a mix of contemporary and classical music.[6] Hare continued to conduct the orchestra for a number of years,[7] while teaching string and orchestral classes at Mount Royal College. He and his wife, pianist Dorothy Swetnam (a survivor of the Halifax Explosion), performed concerts as a duet.[8]
Hare later taught music at the University of Portland.[9] While there he wrote music reviews for the Portland Reporter newspaper.[10]
