Boettcher Concert Hall, is a Concert Hall in Denver, Colorado and is home to the Colorado Symphony. It is named after Colorado native and philanthropist Claude K. Boettcher.
Boettcher was the first symphony hall in the round in the United States. Built in 1978 by Hardy Holzman Pfeiffer Associates, as a home for the Denver Symphony Orchestra, the hall is part of the Denver Performing Arts Complex, which is the second largest performing arts complex in the United States next to Lincoln Center in New York. Boettcher originally opened to mixed reviews. Due to its size in relation to the size of the community it serves, its 2,362 seats are often not completely filled. Tuned acoustically with a full house in mind, Boettcher originally suffered from hot and cold spots when the theater was only partially filled.
The Boettcher Concert Hall is the first symphony hall in-the-round in the United States. It was designed to place the audience close to the stage in a unique environment – 80% of the seats are within 65 feet of the stage. There are no true vertical or horizontal surfaces inside Boettcher Concert Hall; the walls are canted at a slight angle to disperse sound and prevent flutter echoes. On each curved surface of the hall (at approximately four feet high) is a wave-like band, called an undulating acoustical facia. These facias diffuse, reflect and channel sound throughout the venue. Additionally, the acoustical moat, located underneath the stage is essential in the surround design, it acts as a reverberate chamber for low frequency sound. The Canopy features 108 circular discs which is the primary device for distribution of sound to the musicians as well as the audience. These discs effect certain lighting positions on the catwalks and ring hangers. The seats in Boettcher are custom-designed, made from steam-bent wood with their backs varying in height from 42 inches to 48 inches. In 1993, the theater underwent a major acoustical renovation. The height of the seat backs was adjusted, additional acoustic reflectors were added, and acoustic curtains were installed which allow the theater to be tuned for specific performances—even during a performance.
