Harold Hall ("Hal") Robinson (born July 29, 1952) is an American classical double bass player. He is currently the principal bassist of the Philadelphia Orchestra.
Robinson was born in Houston, Texas, the son of Keith Robinson and Dorothe Fowler. Both parents were members of the Houston Symphony Orchestra: his father was the principal bassist, and his mother was a violinist. Hal and all four of his siblings—cellists Sharon and Keith, Jr., and violinists Erica and Kim—became professional string players with notable careers.
Robinson graduated from Robert E. Lee High School in Houston and studied bass at Northwestern University and the Peabody Institute. Among his prominent teachers are Warren Benfield (Chicago Symphony), and Paul Ellison (Houston Symphony).
From 1975 to 1977 he held the position of principal bass of the Albuquerque Symphony (now the New Mexico Symphony Orchestra) and played in the Santa Fe Opera Orchestra. In 1977, he became assistant principal bass of the Houston Symphony Orchestra. During this time he was on the music faculty at the University of Houston. In 1982 Robinson was a prizewinner at the Isle of Man Solo Competition. In 1985 he was appointed by Mstislav Rostropovich to the position of principal bass of the National Symphony Orchestra, where he performed until 1995, when he assumed his present posts as principal bass of the Philadelphia Orchestra and a member of the faculty of the Curtis Institute of Music.
