Clarence Dickinson (1873–1969) was an American composer and organist, primarily associated with classical and sacred music. He was known for his contributions to the choral and organ repertoire, often integrating elements of American folk music and hymnody into his works. Dickinson served as the organist and choirmaster at various churches, most notably at the Church of the Ascension in New York City. Among his notable works are the "Three Preludes for Organ" and a variety of choral compositions, including settings of texts by prominent poets and hymn writers. His hymns and arrangements remain popular in church settings, reflecting his dedication to enhancing the worship experience through music. Dickinson's impact on music lies not only in his compositions but also in his role as an educator and advocate for the organ as a significant instrument in both sacred and concert settings. He contributed to the development of organ music in the early 20th century and influenced future generations of organists and composers. His work continues to resonate within church music traditions, making him a notable figure in American sacred music history.
