Frederick Arthur Gore Ouseley (1825–1889) was an English composer, organist, and music educator known for his contributions to the Anglican choral tradition. Primarily associated with the genres of sacred music and choral works, Ouseley was a prominent figure in the Victorian era's music scene. He is best known for his anthems, hymn tunes, and liturgical music, with notable works including the anthem "O Lord, support us," and the hymn tune "St. Oswald." Ouseley also composed a variety of instrumental works, including orchestral pieces and chamber music, though his legacy is largely rooted in his choral compositions. In addition to his compositions, Ouseley was instrumental in music education. He founded the School of Church Music at St. Mary’s, Oxford, fostering a generation of musicians dedicated to church music. His efforts significantly influenced the development of choral music in England, emphasizing the importance of quality choral training and performance. Ouseley's work remains a vital part of the Anglican choral repertoire, reflecting the rich musical heritage of 19th-century England.
