Robert Winter discusses the evolution of musical spaces. He shows photographs of historic venues for music, outdoor spaces, concert halls, and opera houses. In addition to describing various buildings, he plays samples of classical music by composers from the same period. He describes the reverberation caused by the structure and hard reflective surfaces in churches as a highly prized goal. Winter describes acoustical integrity and the ability of architects to build spaces for music. He explains, “the biggest enemy of sound in the 20th Century, I believe has been plywood paneling.” He describes the acoustics of Carnegie Hall in New York City. Winter shows the Philharmonie in Berlin and calls it, “acoustically sensational.” He also talks about Le Corbusier’s Philips Pavilion at the 1958 World’s Fair in Brussels. Winter believes, “architects need to have their own musical consciousness” in order to design music spaces.
