Stage Risers
While orchestra risers are present in historical halls such as in the Vienna Musikvereinssaal, our use of the deeply arched, semicircular risers used in modern halls was derived from the Berlin Philharmonie, where their original purpose was not acoustic, but visual. Herbert von Karajan produced and directed films of orchestra performances and lifted the instruments at the rear of the stage in order to better see them and to fill the frame. The incidental acoustical improvement was noticeable. In particular, sound from the strings and woodwinds is better able to project, improving their balance with the brass section. The vertical faces of the risers act as an additional reflecting surface to project sound outward towards the audience. Since the brass section sits on the last platform with no riser behind them, this vertical face is absent, further helping to boost the strings and woodwinds in comparison. While we have not conducted rigorous studies, a rise of more than 25 cm per step is appropriate.
