The orchestra pit of Bayreuth: Myths and facts.

The Bayreuth Festspielhaus (inaugurated in 1876) is the culmination of an extensive developmental journey, representing a milestone for technical and functional evolution of performance space. Its architecture reflects the intent of Richard Wagner (1813-1883) to craft a new German opera house: among other innovations, the Festspielhaus introduced an orchestra pit. Although the idea of the orchestra pit is not original, the sum of the outcomes of the Festspielhaus has made this solution revolutionary, beyond the boundaries of the site-specific nature of the building. Focusing on architectural acoustics, this study seeks to emphasize the impact of the orchestra pit. Based on measurements, the multiple functions performed by the orchestra pit are highlighted, starting with balancing the sound of a large orchestra and the intelligibility needs of the soloist's voice. A large amount of non-technical literature was deeply investigated to find matches with objective results and complementary knowledge, such as the limited communication between the orchestra pit and the stage and the poor listening from the conductor's position. Like many groundbreaking processes, the Bayreuth orchestra pit was shown to brilliantly solve acoustic challenges but also evidences limitations, progressively abandoned in the natural evolutionary process of performance spaces.
