Hal takes its name from Boston’s Symphony Hall. Opened in 1900, it is one of the most acoustically perfect buildings in the world. It is home to the Boston Symphony Orchestra and the Boston Pops. Before construction started on Symphony Hall, Wallace Clement Sabine, a physics professor at Harvard University, was hired to work as acoustical consultant with the architectural firm designing the hall. Sabine used mathematical formulas to help design the building to be as in tune as the instruments that play there. Hal was christened in 2003 by famous Pops Conductor Keith Lockhart.
