the first question any lover of classical music usually asb an acoustician is, "Which are the best halls in the world?" The response-the three halls rated highest by world-praised conductors and music critics of the largest newspapers were built in 1870, 1888, and 1900-always prompts the next query: "Why are those so good while many halls built after 1950 seem to be mediocre or failures?" You will find answers to these questions in this book the result of a half-century's
research into the very complex field of acoustics of halls for music.
