Robert Fayrfax (c. 1464–1521) was an English composer of the late Renaissance, known primarily for his contributions to choral music. His genre predominantly encompasses sacred music, with a focus on polyphonic settings of liturgical texts. Fayrfax was a significant figure in the development of English choral music during the early 16th century, with a style that combined intricate counterpoint and rich harmonies. Notable works include the "Missa O quam gloriosum," which showcases his mastery of polyphony, and several motets, such as "In te, Domine, speravi." His music often reflects the influence of continental styles, particularly those from the Franco-Flemish tradition, while also incorporating distinctly English elements. Fayrfax's impact on music lies in his role in the establishment of the English choral tradition and his influence on subsequent composers, including those at the royal court. He served as a composer for the Chapel Royal and was associated with notable figures of his time, including King Henry VIII. His works have been preserved and performed, contributing to the understanding of early Tudor music and its evolution.
