As a composer, Lionel Rogg started out in the early 1950's writing in the serial style favored at that time. His activities as composer broke off as his career as an organist picked up, and Rogg resumed writing only in the 1980's. Casting off the doctrine of serialism in these later works, Rogg's music incorporates a broad number of stylistic elements, adding up to a result that defies distinct categorization.
Rogg favors the term "free" in describing his music and these newer compositions have gained wide acceptance in Europe.
In his attitude towards serialism, Rogg seems to have been a bit ahead of younger composers working within the post-modern era. His catalogue contains numerous works for organ, piano, for choir and orchestra and for chamber music.
