Frederick Flaxington Harker was an American organist and composer who originally came from Scotland. He moved to the United States when he was 25 years old. After arriving, he took the role of Organist and Choirmaster at All Souls Episcopal Church in Asheville, North Carolina. This position marked an important part of his musical career in America. Harker's move from Scotland to the U.S. allowed him to continue working in music within a new community. Harker created many kinds of music during his career. He composed cantatas, anthems, and choruses, as well as songs meant for both religious and regular settings. In addition to his vocal music, he also wrote some pieces for the organ. His range as a composer included both sacred and secular works, showing his ability to write music suited for different purposes and audiences. Besides composing, Harker was involved in music publishing. He worked as a music editor for G. Schirmer Inc., a well-known publishing company. In this role, he edited a variety of choral and organ works, helping to prepare music for performance and study. One significant project he worked on was editing John Stainer's classic text for organ students called The Organ. This work remains a notable resource for learning the organ.
