It was widely performed in America; and also in England, in 1899 at Chester, and at the Three Choirs Festival at Worcester, the latter an honour never before paid an American composer. European critics called it one of the finest of American compositions. While he is mostly remembered for this single work, he was a prolific and versatile composer in a mostly conservative Germanic tradition, writing two operas, songs, organ and incidental music, and a copious quantity of works for chorus and orchestra. Influences in his compositions include Mendelssohn, Brahms, Wagner, as well as Debussy and Elgar in some works which he composed closer to 1900. During his lifetime he was considered to be the finest composer in the United States, a superior craftsman writing in the most advanced style. In 1892, Parker composed the hymn tune "Auburndale" in celebration of the laying of the cornerstone of the new church building of the Episcopal parish he was baptised in, Parish of the Messiah. His father, Charles Edward Parker, had been the architect for that congregation's chapel; famed Episcopal bishop Phillips Brooks laid the cornerstone. "Auburndale" was later published in the 1916 Hymnal ("The Messiah Miracle: A History The Church of the Messiah of West Newton and Auburndale 1871–1971," privately published, 1971). Parker entered his opera, Mona, into a contest at the Metropolitan Opera winning the prize for best composition in 1911. He won 10,000 dollars and his opera was performed by the company. Mona premiered on March 14, 1912 and ran for four performances. The title role was taken by Louise Homer. He won the Los Angeles $10,000 prize for his opera Fairyland.
