William Francis McBeth (March 9, 1933 – January 6, 2012) was a prolific American composer, whose wind band works are highly respected. His primary musical influences included Clifton Williams, Bernard Rogers, and Howard Hanson. The popularity of his works in the United States during the last half of the twentieth century led to many invitations and appearances as a guest conductor, where he often conducted the premiere performances of some of his compositions, the majority of which were commissioned. His conducting activities have taken him to forty-eight states, three Canadian provinces, Japan, and Australia. At one time, his "Double Pyramid Balance System" was a widely used pedagogical tool in the concert band world.From 1957 until his retirement in 1996, McBeth taught at Ouachita Baptist University in Arkadelphia, Arkansas.
