George Thomas Smart (1776-1867) was an English composer and organist, primarily associated with the genres of choral and sacred music. He is best known for his contributions to the development of the English choral tradition during the early 19th century. One of his most notable works is the anthem "O, for a Thousand Tongues to Sing," which showcases his ability to blend lyrical melodies with rich harmonies. Smart's impact on music extends beyond his compositions; he was a prominent figure in the music scene of his time, known for his role as an organist at various churches, including St. Martin-in-the-Fields in London. He also contributed to the establishment of choral societies and was involved in the promotion of contemporary music and composers of his era. In addition to his choral works, Smart composed piano music, songs, and orchestral pieces, although his sacred music remains the most recognized aspect of his legacy. His efforts helped to elevate the standards of choral performance and composition in England, influencing subsequent generations of composers and musicians.
