one of the first American composers to become interested in the music and folklore of the American Indian.

By age 13 Cadman was studying the piano and organ. At about age 19 he met Nellie Richmond Eberhart, who would write most of his song lyrics and opera librettos. In his early 20s he held various jobs, pursuing music studies as he could. From 1908 to 1910 he was music critic for the Pittsburgh Dispatch. A visit to an Omaha Indian reservation reinforced an earlier interest in Indian music. He made recordings of Indian music and from 1909 to 1923 gave lecture-recitals with Tsianina Redfeather, an Indian singer, in both America and Europe.

From 1917 he lived in California and in 1924 took a doctorate in music at the University of Southern California. His songs “At Dawning” (1906) and “From the Land of Sky-Blue Water” (1908) became highly popular. His 1918 opera Shanewis (The Robin Woman) was the first American opera to play two seasons at New York City's Metropolitan Opera. Other works include the operatic cantata The Sunset Trail (1925) and the operas A Witch of Salem (1926) and The Willow Tree (1931), the first American opera written for radio; the American Suite for strings; the Thunderbird Suite for piano; and the cantata The Vision of Sir Launfal.
