Ivar Henning was best known as a composer for solo piano, chamber orchestra, instrumental, and vocal music. His style was thought to be independent and advanced for its time. His music is described as poetic, impressionistic, and full of fantasy, influenced by Debussy, Grieg, and Liszt His work focused on technical and stylistic aspects rather than the more popular romantic style. In 1917 he was elected into the Swedish Royal Academy of Music.
