Tracy Y. Cannon influenced Latter-day Saint hymnbook history by steering away from the pioneer folk tunes of his grandfather, Brigham Young, toward a refined, European-influenced aesthetic. As chairman of the General Music Committee, Cannon professionalized the Church’s musical identity, famously pivoting the 1948 hymnal to mirror the harmonic elegance of Lutheran and Anglican traditions. This strategic move established the solemn, organ-centric sound that defined worship for the rest of the 20th century. In this interview, biographer Shelby Fisher discusses Tracy Y. Cannon’s training as a Mormon organist and explains how he modernized the Church’s musical tradition in a way that can still be seen today.
