In 1925, the Canadian Performing Rights Society was formed to administer public performance and royalties for composers and lyricists. It became known as the Composers, Authors and Publishers Association of Canada (CAPAC). Toronto-born Murray Adaskin (1906–2002) was a violinist, composer, conductor and teacher at the University of Saskatchewan. From 1923 to 1936 he was an orchestral and chamber musician with the Toronto Symphony Orchestra, he was later named head of music at the University of Saskatchewan. He was a composer-in-residence at the University of Saskatchewan, the first appointment of this type in Canada.
By the end of World War II, "mountaineer" string band music known as bluegrass had emerged when Bill Monroe joined with Lester Flatt and Earl Scruggs, introduced by Roy Acuff at the Grand Ole Opry. That was the ordination of bluegrass music and how Bill Monroe became to be known as the "Father of Country Music." Gospel music, too, remained a popular component of bluegrass and other sorts of country music. Red Foley, the biggest country star following World War II, had one of the first million-selling gospel hits ("Peace in the Valley") and also sang boogie, blues and rockabilly. In the post-war period, country music was called "folk" in the trades, and "hillbilly" within the industry. In 1944, The Billboard replaced the term "hillbilly" with "folk songs and blues," and switched to "country" or "country and Western" in 1949. https://www.youtube.com/watch?v=hyNAvdnZ5Ec
